Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1031560, here are decompositions:
- 11 + 1031549 = 1031560
- 29 + 1031531 = 1031560
- 53 + 1031507 = 1031560
- 71 + 1031489 = 1031560
- 83 + 1031477 = 1031560
- 113 + 1031447 = 1031560
- 137 + 1031423 = 1031560
- 149 + 1031411 = 1031560
Showing the first eight; more decompositions exist.
