Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22810, here are decompositions:

3 + 22807 = 22810
23 + 22787 = 22810
41 + 22769 = 22810
59 + 22751 = 22810
71 + 22739 = 22810
83 + 22727 = 22810
89 + 22721 = 22810
101 + 22709 = 22810

Showing the first eight; more decompositions exist.
