Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7628, here are decompositions:
- 7 + 7621 = 7628
- 37 + 7591 = 7628
- 67 + 7561 = 7628
- 79 + 7549 = 7628
- 139 + 7489 = 7628
- 151 + 7477 = 7628
- 211 + 7417 = 7628
- 277 + 7351 = 7628
Showing the first eight; more decompositions exist.
