Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616194, here are decompositions:

11 + 31616183 = 31616194
173 + 31616021 = 31616194
347 + 31615847 = 31616194
431 + 31615763 = 31616194
881 + 31615313 = 31616194
977 + 31615217 = 31616194
983 + 31615211 = 31616194
1031 + 31615163 = 31616194

Showing the first eight; more decompositions exist.
