Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 464784, here are decompositions:
- 7 + 464777 = 464784
- 11 + 464773 = 464784
- 13 + 464771 = 464784
- 17 + 464767 = 464784
- 31 + 464753 = 464784
- 37 + 464747 = 464784
- 43 + 464741 = 464784
- 97 + 464687 = 464784
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 464,784 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 464784 first appears in π at position 883,261 of the decimal expansion (the 883,261ordinal-suffix:st 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.
