Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742658, here are decompositions:

5 + 8742653 = 8742658
107 + 8742551 = 8742658
257 + 8742401 = 8742658
311 + 8742347 = 8742658
461 + 8742197 = 8742658
599 + 8742059 = 8742658
647 + 8742011 = 8742658
797 + 8741861 = 8742658

Showing the first eight; more decompositions exist.
