Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731750, here are decompositions:

29 + 8731721 = 8731750
89 + 8731661 = 8731750
107 + 8731643 = 8731750
113 + 8731637 = 8731750
179 + 8731571 = 8731750
239 + 8731511 = 8731750
257 + 8731493 = 8731750
317 + 8731433 = 8731750

Showing the first eight; more decompositions exist.
