Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738730, here are decompositions:
- 17 + 8738713 = 8738730
- 19 + 8738711 = 8738730
- 23 + 8738707 = 8738730
- 59 + 8738671 = 8738730
- 71 + 8738659 = 8738730
- 89 + 8738641 = 8738730
- 139 + 8738591 = 8738730
- 149 + 8738581 = 8738730
Showing the first eight; more decompositions exist.
