Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1031550, here are decompositions:
- 17 + 1031533 = 1031550
- 19 + 1031531 = 1031550
- 29 + 1031521 = 1031550
- 43 + 1031507 = 1031550
- 61 + 1031489 = 1031550
- 67 + 1031483 = 1031550
- 71 + 1031479 = 1031550
- 73 + 1031477 = 1031550
Showing the first eight; more decompositions exist.
