Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8612130, here are decompositions:

11 + 8612119 = 8612130
31 + 8612099 = 8612130
41 + 8612089 = 8612130
71 + 8612059 = 8612130
73 + 8612057 = 8612130
97 + 8612033 = 8612130
139 + 8611991 = 8612130
227 + 8611903 = 8612130

Showing the first eight; more decompositions exist.
