Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71490, here are decompositions:
- 7 + 71483 = 71490
- 11 + 71479 = 71490
- 17 + 71473 = 71490
- 19 + 71471 = 71490
- 37 + 71453 = 71490
- 47 + 71443 = 71490
- 53 + 71437 = 71490
- 61 + 71429 = 71490
Showing the first eight; more decompositions exist.
