Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731172, here are decompositions:

19 + 8731153 = 8731172
31 + 8731141 = 8731172
61 + 8731111 = 8731172
103 + 8731069 = 8731172
223 + 8730949 = 8731172
271 + 8730901 = 8731172
283 + 8730889 = 8731172
313 + 8730859 = 8731172

Showing the first eight; more decompositions exist.
