Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8613172, here are decompositions:

11 + 8613161 = 8613172
23 + 8613149 = 8613172
83 + 8613089 = 8613172
131 + 8613041 = 8613172
311 + 8612861 = 8613172
419 + 8612753 = 8613172
443 + 8612729 = 8613172
461 + 8612711 = 8613172

Showing the first eight; more decompositions exist.
