Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450196, here are decompositions:

79 + 31450117 = 31450196
97 + 31450099 = 31450196
103 + 31450093 = 31450196
139 + 31450057 = 31450196
163 + 31450033 = 31450196
229 + 31449967 = 31450196
373 + 31449823 = 31450196
439 + 31449757 = 31450196

Showing the first eight; more decompositions exist.
