Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731668, here are decompositions:

7 + 8731661 = 8731668
31 + 8731637 = 8731668
41 + 8731627 = 8731668
59 + 8731609 = 8731668
61 + 8731607 = 8731668
89 + 8731579 = 8731668
97 + 8731571 = 8731668
137 + 8731531 = 8731668

Showing the first eight; more decompositions exist.
