Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448196, here are decompositions:

5 + 31448191 = 31448196
47 + 31448149 = 31448196
127 + 31448069 = 31448196
139 + 31448057 = 31448196
163 + 31448033 = 31448196
173 + 31448023 = 31448196
179 + 31448017 = 31448196
229 + 31447967 = 31448196

Showing the first eight; more decompositions exist.
