Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8629740, here are decompositions:
- 29 + 8629711 = 8629740
- 59 + 8629681 = 8629740
- 61 + 8629679 = 8629740
- 79 + 8629661 = 8629740
- 89 + 8629651 = 8629740
- 103 + 8629637 = 8629740
- 127 + 8629613 = 8629740
- 157 + 8629583 = 8629740
Showing the first eight; more decompositions exist.
