Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667558, here are decompositions:
- 19 + 8667539 = 8667558
- 37 + 8667521 = 8667558
- 47 + 8667511 = 8667558
- 61 + 8667497 = 8667558
- 101 + 8667457 = 8667558
- 127 + 8667431 = 8667558
- 131 + 8667427 = 8667558
- 139 + 8667419 = 8667558
Showing the first eight; more decompositions exist.
