Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8650140, here are decompositions:

11 + 8650129 = 8650140
17 + 8650123 = 8650140
19 + 8650121 = 8650140
53 + 8650087 = 8650140
89 + 8650051 = 8650140
101 + 8650039 = 8650140
113 + 8650027 = 8650140
137 + 8650003 = 8650140

Showing the first eight; more decompositions exist.
