Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448112, here are decompositions:

41 + 31448071 = 31448112
43 + 31448069 = 31448112
79 + 31448033 = 31448112
89 + 31448023 = 31448112
149 + 31447963 = 31448112
151 + 31447961 = 31448112
181 + 31447931 = 31448112
211 + 31447901 = 31448112

Showing the first eight; more decompositions exist.
