Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739660, here are decompositions:

23 + 8739637 = 8739660
37 + 8739623 = 8739660
43 + 8739617 = 8739660
53 + 8739607 = 8739660
131 + 8739529 = 8739660
157 + 8739503 = 8739660
179 + 8739481 = 8739660
197 + 8739463 = 8739660

Showing the first eight; more decompositions exist.
