Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 626, here are decompositions:
- 7 + 619 = 626
- 13 + 613 = 626
- 19 + 607 = 626
- 79 + 547 = 626
- 103 + 523 = 626
- 127 + 499 = 626
- 139 + 487 = 626
- 163 + 463 = 626
Showing the first eight; more decompositions exist.
