Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021984, here are decompositions:
- 11 + 1021973 = 1021984
- 23 + 1021961 = 1021984
- 191 + 1021793 = 1021984
- 311 + 1021673 = 1021984
- 443 + 1021541 = 1021984
- 521 + 1021463 = 1021984
- 617 + 1021367 = 1021984
- 653 + 1021331 = 1021984
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 1,021,984 and was likely granted around 1912.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
