Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639202, here are decompositions:

31 + 8639171 = 8639202
41 + 8639161 = 8639202
53 + 8639149 = 8639202
59 + 8639143 = 8639202
71 + 8639131 = 8639202
79 + 8639123 = 8639202
83 + 8639119 = 8639202
113 + 8639089 = 8639202

Showing the first eight; more decompositions exist.
