Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7646, here are decompositions:
- 3 + 7643 = 7646
- 7 + 7639 = 7646
- 43 + 7603 = 7646
- 73 + 7573 = 7646
- 97 + 7549 = 7646
- 109 + 7537 = 7646
- 139 + 7507 = 7646
- 157 + 7489 = 7646
Showing the first eight; more decompositions exist.
