Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1524, here are decompositions:
- 13 + 1511 = 1524
- 31 + 1493 = 1524
- 37 + 1487 = 1524
- 41 + 1483 = 1524
- 43 + 1481 = 1524
- 53 + 1471 = 1524
- 71 + 1453 = 1524
- 73 + 1451 = 1524
Showing the first eight; more decompositions exist.
