Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 464720, here are decompositions:
- 73 + 464647 = 464720
- 103 + 464617 = 464720
- 163 + 464557 = 464720
- 181 + 464539 = 464720
- 199 + 464521 = 464720
- 241 + 464479 = 464720
- 283 + 464437 = 464720
- 307 + 464413 = 464720
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 464,720 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 464720 first appears in π at position 390,250 of the decimal expansion (the 390,250ordinal-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.
