Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1510, here are decompositions:
- 11 + 1499 = 1510
- 17 + 1493 = 1510
- 23 + 1487 = 1510
- 29 + 1481 = 1510
- 59 + 1451 = 1510
- 71 + 1439 = 1510
- 83 + 1427 = 1510
- 101 + 1409 = 1510
Showing the first eight; more decompositions exist.
