Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77628, here are decompositions:
- 7 + 77621 = 77628
- 11 + 77617 = 77628
- 17 + 77611 = 77628
- 37 + 77591 = 77628
- 41 + 77587 = 77628
- 59 + 77569 = 77628
- 71 + 77557 = 77628
- 79 + 77549 = 77628
Showing the first eight; more decompositions exist.
