Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7572, here are decompositions:
- 11 + 7561 = 7572
- 13 + 7559 = 7572
- 23 + 7549 = 7572
- 31 + 7541 = 7572
- 43 + 7529 = 7572
- 73 + 7499 = 7572
- 83 + 7489 = 7572
- 113 + 7459 = 7572
Showing the first eight; more decompositions exist.
