Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621032, here are decompositions:

23 + 8621009 = 8621032
59 + 8620973 = 8621032
83 + 8620949 = 8621032
89 + 8620943 = 8621032
191 + 8620841 = 8621032
293 + 8620739 = 8621032
311 + 8620721 = 8621032
359 + 8620673 = 8621032

Showing the first eight; more decompositions exist.
