Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616190, here are decompositions:

7 + 31616183 = 31616190
17 + 31616173 = 31616190
41 + 31616149 = 31616190
61 + 31616129 = 31616190
131 + 31616059 = 31616190
149 + 31616041 = 31616190
157 + 31616033 = 31616190
167 + 31616023 = 31616190

Showing the first eight; more decompositions exist.
