Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672, here are decompositions:
- 3 + 8669 = 8672
- 31 + 8641 = 8672
- 43 + 8629 = 8672
- 73 + 8599 = 8672
- 109 + 8563 = 8672
- 151 + 8521 = 8672
- 211 + 8461 = 8672
- 229 + 8443 = 8672
Showing the first eight; more decompositions exist.
