Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616170, here are decompositions:

41 + 31616129 = 31616170
101 + 31616069 = 31616170
137 + 31616033 = 31616170
149 + 31616021 = 31616170
191 + 31615979 = 31616170
197 + 31615973 = 31616170
251 + 31615919 = 31616170
587 + 31615583 = 31616170

Showing the first eight; more decompositions exist.
