Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540940, here are decompositions:
- 89 + 540851 = 540940
- 131 + 540809 = 540940
- 137 + 540803 = 540940
- 167 + 540773 = 540940
- 227 + 540713 = 540940
- 251 + 540689 = 540940
- 263 + 540677 = 540940
- 311 + 540629 = 540940
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 540,940 and was likely granted around 1894.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 540940 first appears in π at position 297,016 of the decimal expansion (the 297,016ordinal-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.
