Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 947978, here are decompositions:

  • 19 + 947959 = 947978
  • 61 + 947917 = 947978
  • 67 + 947911 = 947978
  • 127 + 947851 = 947978
  • 271 + 947707 = 947978
  • 331 + 947647 = 947978
  • 337 + 947641 = 947978
  • 439 + 947539 = 947978

Showing the first eight; more decompositions exist.

Possible US patent number

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 947,978 and was likely granted around 1909.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 947978 first appears in π at position 419,080 of the decimal expansion (the 419,080ordinal-suffix:th digit after the integer 3).

Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
