Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621134, here are decompositions:

47 + 8621087 = 8621134
83 + 8621051 = 8621134
191 + 8620943 = 8621134
293 + 8620841 = 8621134
443 + 8620691 = 8621134
461 + 8620673 = 8621134
503 + 8620631 = 8621134
563 + 8620571 = 8621134

Showing the first eight; more decompositions exist.
