Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616112, here are decompositions:

43 + 31616069 = 31616112
53 + 31616059 = 31616112
71 + 31616041 = 31616112
79 + 31616033 = 31616112
89 + 31616023 = 31616112
103 + 31616009 = 31616112
113 + 31615999 = 31616112
139 + 31615973 = 31616112

Showing the first eight; more decompositions exist.
