Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 584640, here are decompositions:
- 13 + 584627 = 584640
- 19 + 584621 = 584640
- 31 + 584609 = 584640
- 37 + 584603 = 584640
- 41 + 584599 = 584640
- 47 + 584593 = 584640
- 53 + 584587 = 584640
- 79 + 584561 = 584640
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 584,640 and was likely granted around 1896.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 584640 first appears in π at position 349,957 of the decimal expansion (the 349,957ordinal-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.
