Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448234, here are decompositions:

43 + 31448191 = 31448234
73 + 31448161 = 31448234
163 + 31448071 = 31448234
211 + 31448023 = 31448234
271 + 31447963 = 31448234
277 + 31447957 = 31448234
283 + 31447951 = 31448234
331 + 31447903 = 31448234

Showing the first eight; more decompositions exist.
