Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8612738, here are decompositions:

7 + 8612731 = 8612738
31 + 8612707 = 8612738
37 + 8612701 = 8612738
67 + 8612671 = 8612738
97 + 8612641 = 8612738
109 + 8612629 = 8612738
157 + 8612581 = 8612738
241 + 8612497 = 8612738

Showing the first eight; more decompositions exist.
