Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80628, here are decompositions:
- 7 + 80621 = 80628
- 17 + 80611 = 80628
- 29 + 80599 = 80628
- 61 + 80567 = 80628
- 71 + 80557 = 80628
- 101 + 80527 = 80628
- 137 + 80491 = 80628
- 139 + 80489 = 80628
Showing the first eight; more decompositions exist.
