Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637932, here are decompositions:

3 + 8637929 = 8637932
103 + 8637829 = 8637932
313 + 8637619 = 8637932
409 + 8637523 = 8637932
439 + 8637493 = 8637932
613 + 8637319 = 8637932
631 + 8637301 = 8637932
643 + 8637289 = 8637932

Showing the first eight; more decompositions exist.
