Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655072, here are decompositions:

31 + 8655041 = 8655072
43 + 8655029 = 8655072
61 + 8655011 = 8655072
113 + 8654959 = 8655072
131 + 8654941 = 8655072
199 + 8654873 = 8655072
233 + 8654839 = 8655072
263 + 8654809 = 8655072

Showing the first eight; more decompositions exist.
