Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8613642, here are decompositions:

19 + 8613623 = 8613642
71 + 8613571 = 8613642
83 + 8613559 = 8613642
113 + 8613529 = 8613642
179 + 8613463 = 8613642
181 + 8613461 = 8613642
251 + 8613391 = 8613642
263 + 8613379 = 8613642

Showing the first eight; more decompositions exist.
