Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739646, here are decompositions:

23 + 8739623 = 8739646
29 + 8739617 = 8739646
257 + 8739389 = 8739646
347 + 8739299 = 8739646
449 + 8739197 = 8739646
479 + 8739167 = 8739646
593 + 8739053 = 8739646
683 + 8738963 = 8739646

Showing the first eight; more decompositions exist.
