Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645632, here are decompositions:

53 + 8645579 = 8645632
89 + 8645543 = 8645632
251 + 8645381 = 8645632
389 + 8645243 = 8645632
491 + 8645141 = 8645632
509 + 8645123 = 8645632
641 + 8644991 = 8645632
683 + 8644949 = 8645632

Showing the first eight; more decompositions exist.
