Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731124, here are decompositions:

13 + 8731111 = 8731124
97 + 8731027 = 8731124
211 + 8730913 = 8731124
223 + 8730901 = 8731124
277 + 8730847 = 8731124
331 + 8730793 = 8731124
433 + 8730691 = 8731124
463 + 8730661 = 8731124

Showing the first eight; more decompositions exist.
