Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1490, here are decompositions:
- 3 + 1487 = 1490
- 7 + 1483 = 1490
- 19 + 1471 = 1490
- 31 + 1459 = 1490
- 37 + 1453 = 1490
- 43 + 1447 = 1490
- 61 + 1429 = 1490
- 67 + 1423 = 1490
Showing the first eight; more decompositions exist.
