Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 984720, here are decompositions:
- 13 + 984707 = 984720
- 17 + 984703 = 984720
- 19 + 984701 = 984720
- 31 + 984689 = 984720
- 53 + 984667 = 984720
- 103 + 984617 = 984720
- 109 + 984611 = 984720
- 127 + 984593 = 984720
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 984,720 and was likely granted around 1910.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
