Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 940438, here are decompositions:
- 17 + 940421 = 940438
- 89 + 940349 = 940438
- 137 + 940301 = 940438
- 167 + 940271 = 940438
- 179 + 940259 = 940438
- 197 + 940241 = 940438
- 269 + 940169 = 940438
- 281 + 940157 = 940438
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 940,438 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 940438 first appears in π at position 360,342 of the decimal expansion (the 360,342ordinal-suffix:nd 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.
