Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450194, here are decompositions:

31 + 31450163 = 31450194
53 + 31450141 = 31450194
101 + 31450093 = 31450194
137 + 31450057 = 31450194
151 + 31450043 = 31450194
163 + 31450031 = 31450194
173 + 31450021 = 31450194
227 + 31449967 = 31450194

Showing the first eight; more decompositions exist.
