Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 477838, here are decompositions:

  • 17 + 477821 = 477838
  • 29 + 477809 = 477838
  • 41 + 477797 = 477838
  • 47 + 477791 = 477838
  • 71 + 477767 = 477838
  • 107 + 477731 = 477838
  • 167 + 477671 = 477838
  • 281 + 477557 = 477838

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 477,838 and was likely granted around 1892.

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

Position in π

The digit sequence 477838 first appears in π at position 141,740 of the decimal expansion (the 141,740ordinal-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.
