Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655090, here are decompositions:

19 + 8655071 = 8655090
43 + 8655047 = 8655090
53 + 8655037 = 8655090
61 + 8655029 = 8655090
79 + 8655011 = 8655090
83 + 8655007 = 8655090
109 + 8654981 = 8655090
131 + 8654959 = 8655090

Showing the first eight; more decompositions exist.
