Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742930, here are decompositions:
- 11 + 8742919 = 8742930
- 13 + 8742917 = 8742930
- 43 + 8742887 = 8742930
- 73 + 8742857 = 8742930
- 83 + 8742847 = 8742930
- 109 + 8742821 = 8742930
- 113 + 8742817 = 8742930
- 151 + 8742779 = 8742930
Showing the first eight; more decompositions exist.
