Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731224, here are decompositions:

11 + 8731213 = 8731224
13 + 8731211 = 8731224
23 + 8731201 = 8731224
37 + 8731187 = 8731224
71 + 8731153 = 8731224
83 + 8731141 = 8731224
113 + 8731111 = 8731224
127 + 8731097 = 8731224

Showing the first eight; more decompositions exist.
