Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1514, here are decompositions:
- 3 + 1511 = 1514
- 31 + 1483 = 1514
- 43 + 1471 = 1514
- 61 + 1453 = 1514
- 67 + 1447 = 1514
- 193 + 1321 = 1514
- 211 + 1303 = 1514
- 223 + 1291 = 1514
Showing the first eight; more decompositions exist.
