Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731662, here are decompositions:

19 + 8731643 = 8731662
53 + 8731609 = 8731662
83 + 8731579 = 8731662
131 + 8731531 = 8731662
151 + 8731511 = 8731662
229 + 8731433 = 8731662
281 + 8731381 = 8731662
293 + 8731369 = 8731662

Showing the first eight; more decompositions exist.
