Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 527878, here are decompositions:

  • 59 + 527819 = 527878
  • 89 + 527789 = 527878
  • 137 + 527741 = 527878
  • 149 + 527729 = 527878
  • 179 + 527699 = 527878
  • 251 + 527627 = 527878
  • 389 + 527489 = 527878
  • 431 + 527447 = 527878

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 527,878 and was likely granted around 1894.

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

Position in π

The digit sequence 527878 first appears in π at position 997,811 of the decimal expansion (the 997,811ordinal-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.
