Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616252, here are decompositions:

79 + 31616173 = 31616252
103 + 31616149 = 31616252
139 + 31616113 = 31616252
193 + 31616059 = 31616252
211 + 31616041 = 31616252
229 + 31616023 = 31616252
331 + 31615921 = 31616252
523 + 31615729 = 31616252

Showing the first eight; more decompositions exist.
