Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448186, here are decompositions:

37 + 31448149 = 31448186
163 + 31448023 = 31448186
199 + 31447987 = 31448186
223 + 31447963 = 31448186
229 + 31447957 = 31448186
283 + 31447903 = 31448186
349 + 31447837 = 31448186
373 + 31447813 = 31448186

Showing the first eight; more decompositions exist.
