Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667628, here are decompositions:
- 17 + 8667611 = 8667628
- 89 + 8667539 = 8667628
- 107 + 8667521 = 8667628
- 131 + 8667497 = 8667628
- 197 + 8667431 = 8667628
- 251 + 8667377 = 8667628
- 257 + 8667371 = 8667628
- 401 + 8667227 = 8667628
Showing the first eight; more decompositions exist.
