Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448232, here are decompositions:

31 + 31448201 = 31448232
41 + 31448191 = 31448232
61 + 31448171 = 31448232
71 + 31448161 = 31448232
83 + 31448149 = 31448232
163 + 31448069 = 31448232
199 + 31448033 = 31448232
269 + 31447963 = 31448232

Showing the first eight; more decompositions exist.
