Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8613628, here are decompositions:

5 + 8613623 = 8613628
11 + 8613617 = 8613628
167 + 8613461 = 8613628
281 + 8613347 = 8613628
347 + 8613281 = 8613628
467 + 8613161 = 8613628
479 + 8613149 = 8613628
521 + 8613107 = 8613628

Showing the first eight; more decompositions exist.
