Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448198, here are decompositions:

7 + 31448191 = 31448198
37 + 31448161 = 31448198
127 + 31448071 = 31448198
181 + 31448017 = 31448198
211 + 31447987 = 31448198
241 + 31447957 = 31448198
541 + 31447657 = 31448198
571 + 31447627 = 31448198

Showing the first eight; more decompositions exist.
