Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1031628, here are decompositions:
- 5 + 1031623 = 1031628
- 19 + 1031609 = 1031628
- 67 + 1031561 = 1031628
- 79 + 1031549 = 1031628
- 97 + 1031531 = 1031628
- 107 + 1031521 = 1031628
- 139 + 1031489 = 1031628
- 149 + 1031479 = 1031628
Showing the first eight; more decompositions exist.
