Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637160, here are decompositions:

29 + 8637131 = 8637160
41 + 8637119 = 8637160
53 + 8637107 = 8637160
101 + 8637059 = 8637160
107 + 8637053 = 8637160
173 + 8636987 = 8637160
239 + 8636921 = 8637160
251 + 8636909 = 8637160

Showing the first eight; more decompositions exist.
