Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637912, here are decompositions:

43 + 8637869 = 8637912
83 + 8637829 = 8637912
163 + 8637749 = 8637912
211 + 8637701 = 8637912
271 + 8637641 = 8637912
293 + 8637619 = 8637912
389 + 8637523 = 8637912
419 + 8637493 = 8637912

Showing the first eight; more decompositions exist.
