Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448074, here are decompositions:

3 + 31448071 = 31448074
5 + 31448069 = 31448074
17 + 31448057 = 31448074
41 + 31448033 = 31448074
107 + 31447967 = 31448074
113 + 31447961 = 31448074
173 + 31447901 = 31448074
263 + 31447811 = 31448074

Showing the first eight; more decompositions exist.
