Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747790, here are decompositions:
- 13 + 8747777 = 8747790
- 31 + 8747759 = 8747790
- 43 + 8747747 = 8747790
- 47 + 8747743 = 8747790
- 53 + 8747737 = 8747790
- 67 + 8747723 = 8747790
- 89 + 8747701 = 8747790
- 101 + 8747689 = 8747790
Showing the first eight; more decompositions exist.
