Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670940, here are decompositions:
- 53 + 8670887 = 8670940
- 71 + 8670869 = 8670940
- 149 + 8670791 = 8670940
- 167 + 8670773 = 8670940
- 197 + 8670743 = 8670940
- 227 + 8670713 = 8670940
- 389 + 8670551 = 8670940
- 431 + 8670509 = 8670940
Showing the first eight; more decompositions exist.
