Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1031520, here are decompositions:
- 13 + 1031507 = 1031520
- 31 + 1031489 = 1031520
- 37 + 1031483 = 1031520
- 41 + 1031479 = 1031520
- 43 + 1031477 = 1031520
- 59 + 1031461 = 1031520
- 73 + 1031447 = 1031520
- 89 + 1031431 = 1031520
Showing the first eight; more decompositions exist.
