Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731644, here are decompositions:

7 + 8731637 = 8731644
17 + 8731627 = 8731644
37 + 8731607 = 8731644
73 + 8731571 = 8731644
113 + 8731531 = 8731644
151 + 8731493 = 8731644
167 + 8731477 = 8731644
197 + 8731447 = 8731644

Showing the first eight; more decompositions exist.
