Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8612142, here are decompositions:

23 + 8612119 = 8612142
43 + 8612099 = 8612142
53 + 8612089 = 8612142
83 + 8612059 = 8612142
103 + 8612039 = 8612142
109 + 8612033 = 8612142
131 + 8612011 = 8612142
151 + 8611991 = 8612142

Showing the first eight; more decompositions exist.
