Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448106, here are decompositions:

37 + 31448069 = 31448106
73 + 31448033 = 31448106
83 + 31448023 = 31448106
89 + 31448017 = 31448106
139 + 31447967 = 31448106
149 + 31447957 = 31448106
269 + 31447837 = 31448106
293 + 31447813 = 31448106

Showing the first eight; more decompositions exist.
