Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 940800, here are decompositions:
- 13 + 940787 = 940800
- 17 + 940783 = 940800
- 19 + 940781 = 940800
- 41 + 940759 = 940800
- 61 + 940739 = 940800
- 67 + 940733 = 940800
- 73 + 940727 = 940800
- 79 + 940721 = 940800
Showing the first eight; more decompositions exist.

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 940,800 and was likely granted around 1909.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 940800 first appears in π at position 81,720 of the decimal expansion (the 81,720ordinal-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.
