Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616090, here are decompositions:

31 + 31616059 = 31616090
43 + 31616047 = 31616090
67 + 31616023 = 31616090
73 + 31616017 = 31616090
97 + 31615993 = 31616090
139 + 31615951 = 31616090
199 + 31615891 = 31616090
241 + 31615849 = 31616090

Showing the first eight; more decompositions exist.
