Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668744, here are decompositions:
- 3 + 8668741 = 8668744
- 5 + 8668739 = 8668744
- 23 + 8668721 = 8668744
- 47 + 8668697 = 8668744
- 101 + 8668643 = 8668744
- 107 + 8668637 = 8668744
- 131 + 8668613 = 8668744
- 167 + 8668577 = 8668744
Showing the first eight; more decompositions exist.
