Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 572, here are decompositions:
- 3 + 569 = 572
- 31 + 541 = 572
- 73 + 499 = 572
- 109 + 463 = 572
- 139 + 433 = 572
- 151 + 421 = 572
- 163 + 409 = 572
- 193 + 379 = 572
Showing the first eight; more decompositions exist.
