Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667646, here are decompositions:
- 5 + 8667641 = 8667646
- 83 + 8667563 = 8667646
- 107 + 8667539 = 8667646
- 149 + 8667497 = 8667646
- 227 + 8667419 = 8667646
- 233 + 8667413 = 8667646
- 269 + 8667377 = 8667646
- 347 + 8667299 = 8667646
Showing the first eight; more decompositions exist.
