Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731664, here are decompositions:

3 + 8731661 = 8731664
37 + 8731627 = 8731664
163 + 8731501 = 8731664
283 + 8731381 = 8731664
433 + 8731231 = 8731664
463 + 8731201 = 8731664
523 + 8731141 = 8731664
751 + 8730913 = 8731664

Showing the first eight; more decompositions exist.
