Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731732, here are decompositions:

11 + 8731721 = 8731732
59 + 8731673 = 8731732
71 + 8731661 = 8731732
89 + 8731643 = 8731732
239 + 8731493 = 8731732
389 + 8731343 = 8731732
419 + 8731313 = 8731732
431 + 8731301 = 8731732

Showing the first eight; more decompositions exist.
