Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15636, here are decompositions:
- 7 + 15629 = 15636
- 17 + 15619 = 15636
- 29 + 15607 = 15636
- 53 + 15583 = 15636
- 67 + 15569 = 15636
- 109 + 15527 = 15636
- 139 + 15497 = 15636
- 163 + 15473 = 15636
Showing the first eight; more decompositions exist.
