Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1043520, here are decompositions:
- 7 + 1043513 = 1043520
- 19 + 1043501 = 1043520
- 31 + 1043489 = 1043520
- 41 + 1043479 = 1043520
- 53 + 1043467 = 1043520
- 67 + 1043453 = 1043520
- 151 + 1043369 = 1043520
- 197 + 1043323 = 1043520
Showing the first eight; more decompositions exist.
