Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731112, here are decompositions:

3 + 8731109 = 8731112
43 + 8731069 = 8731112
73 + 8731039 = 8731112
163 + 8730949 = 8731112
193 + 8730919 = 8731112
199 + 8730913 = 8731112
211 + 8730901 = 8731112
223 + 8730889 = 8731112

Showing the first eight; more decompositions exist.
