Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 940442, here are decompositions:
- 43 + 940399 = 940442
- 73 + 940369 = 940442
- 163 + 940279 = 940442
- 193 + 940249 = 940442
- 241 + 940201 = 940442
- 439 + 940003 = 940442
- 541 + 939901 = 940442
- 571 + 939871 = 940442
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 940,442 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 940442 first appears in π at position 915,538 of the decimal expansion (the 915,538ordinal-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.
