Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 462840, here are decompositions:
- 13 + 462827 = 462840
- 67 + 462773 = 462840
- 101 + 462739 = 462840
- 107 + 462733 = 462840
- 113 + 462727 = 462840
- 127 + 462713 = 462840
- 163 + 462677 = 462840
- 167 + 462673 = 462840
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 462,840 and was likely granted around 1891.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 462840 first appears in π at position 42,238 of the decimal expansion (the 42,238ordinal-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.
