Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8613790, here are decompositions:

47 + 8613743 = 8613790
89 + 8613701 = 8613790
113 + 8613677 = 8613790
167 + 8613623 = 8613790
173 + 8613617 = 8613790
443 + 8613347 = 8613790
461 + 8613329 = 8613790
467 + 8613323 = 8613790

Showing the first eight; more decompositions exist.
