Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731650, here are decompositions:

7 + 8731643 = 8731650
13 + 8731637 = 8731650
23 + 8731627 = 8731650
41 + 8731609 = 8731650
43 + 8731607 = 8731650
71 + 8731579 = 8731650
79 + 8731571 = 8731650
139 + 8731511 = 8731650

Showing the first eight; more decompositions exist.
