Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8613660, here are decompositions:

37 + 8613623 = 8613660
43 + 8613617 = 8613660
89 + 8613571 = 8613660
101 + 8613559 = 8613660
113 + 8613547 = 8613660
131 + 8613529 = 8613660
179 + 8613481 = 8613660
197 + 8613463 = 8613660

Showing the first eight; more decompositions exist.
