Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8706138, here are decompositions:

31 + 8706107 = 8706138
37 + 8706101 = 8706138
59 + 8706079 = 8706138
79 + 8706059 = 8706138
127 + 8706011 = 8706138
131 + 8706007 = 8706138
137 + 8706001 = 8706138
139 + 8705999 = 8706138

Showing the first eight; more decompositions exist.
