Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31451196, here are decompositions:

37 + 31451159 = 31451196
47 + 31451149 = 31451196
149 + 31451047 = 31451196
163 + 31451033 = 31451196
167 + 31451029 = 31451196
199 + 31450997 = 31451196
229 + 31450967 = 31451196
317 + 31450879 = 31451196

Showing the first eight; more decompositions exist.
