Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672730, here are decompositions:
- 7 + 8672723 = 8672730
- 23 + 8672707 = 8672730
- 43 + 8672687 = 8672730
- 71 + 8672659 = 8672730
- 83 + 8672647 = 8672730
- 89 + 8672641 = 8672730
- 109 + 8672621 = 8672730
- 167 + 8672563 = 8672730
Showing the first eight; more decompositions exist.
