Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8613738, here are decompositions:

5 + 8613733 = 8613738
37 + 8613701 = 8613738
61 + 8613677 = 8613738
167 + 8613571 = 8613738
179 + 8613559 = 8613738
191 + 8613547 = 8613738
257 + 8613481 = 8613738
277 + 8613461 = 8613738

Showing the first eight; more decompositions exist.
