Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667790, here are decompositions:
- 83 + 8667707 = 8667790
- 101 + 8667689 = 8667790
- 113 + 8667677 = 8667790
- 137 + 8667653 = 8667790
- 149 + 8667641 = 8667790
- 179 + 8667611 = 8667790
- 227 + 8667563 = 8667790
- 251 + 8667539 = 8667790
Showing the first eight; more decompositions exist.
