Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668740, here are decompositions:
- 19 + 8668721 = 8668740
- 29 + 8668711 = 8668740
- 43 + 8668697 = 8668740
- 53 + 8668687 = 8668740
- 97 + 8668643 = 8668740
- 103 + 8668637 = 8668740
- 127 + 8668613 = 8668740
- 131 + 8668609 = 8668740
Showing the first eight; more decompositions exist.
