Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 26628, here are decompositions:
- 31 + 26597 = 26628
- 37 + 26591 = 26628
- 67 + 26561 = 26628
- 71 + 26557 = 26628
- 89 + 26539 = 26628
- 127 + 26501 = 26628
- 131 + 26497 = 26628
- 139 + 26489 = 26628
Showing the first eight; more decompositions exist.
