Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655672, here are decompositions:

19 + 8655653 = 8655672
23 + 8655649 = 8655672
31 + 8655641 = 8655672
41 + 8655631 = 8655672
43 + 8655629 = 8655672
61 + 8655611 = 8655672
239 + 8655433 = 8655672
251 + 8655421 = 8655672

Showing the first eight; more decompositions exist.
