Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 984840, here are decompositions:
- 23 + 984817 = 984840
- 79 + 984761 = 984840
- 83 + 984757 = 984840
- 107 + 984733 = 984840
- 137 + 984703 = 984840
- 139 + 984701 = 984840
- 151 + 984689 = 984840
- 173 + 984667 = 984840
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 984,840 and was likely granted around 1910.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 984840 first appears in π at position 697,963 of the decimal expansion (the 697,963ordinal-suffix:rd 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.
