Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731646, here are decompositions:

3 + 8731643 = 8731646
19 + 8731627 = 8731646
37 + 8731609 = 8731646
67 + 8731579 = 8731646
199 + 8731447 = 8731646
229 + 8731417 = 8731646
277 + 8731369 = 8731646
283 + 8731363 = 8731646

Showing the first eight; more decompositions exist.
