Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637148, here are decompositions:

17 + 8637131 = 8637148
29 + 8637119 = 8637148
41 + 8637107 = 8637148
89 + 8637059 = 8637148
131 + 8637017 = 8637148
227 + 8636921 = 8637148
239 + 8636909 = 8637148
347 + 8636801 = 8637148

Showing the first eight; more decompositions exist.
