Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8659128, here are decompositions:

7 + 8659121 = 8659128
29 + 8659099 = 8659128
31 + 8659097 = 8659128
61 + 8659067 = 8659128
67 + 8659061 = 8659128
109 + 8659019 = 8659128
131 + 8658997 = 8659128
139 + 8658989 = 8659128

Showing the first eight; more decompositions exist.
