Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667780, here are decompositions:
- 47 + 8667733 = 8667780
- 53 + 8667727 = 8667780
- 59 + 8667721 = 8667780
- 73 + 8667707 = 8667780
- 83 + 8667697 = 8667780
- 103 + 8667677 = 8667780
- 127 + 8667653 = 8667780
- 139 + 8667641 = 8667780
Showing the first eight; more decompositions exist.
