Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 76680, here are decompositions:
- 7 + 76673 = 76680
- 13 + 76667 = 76680
- 29 + 76651 = 76680
- 31 + 76649 = 76680
- 73 + 76607 = 76680
- 83 + 76597 = 76680
- 101 + 76579 = 76680
- 137 + 76543 = 76680
Showing the first eight; more decompositions exist.
