Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472106, here are decompositions:

37 + 31472069 = 31472106
53 + 31472053 = 31472106
103 + 31472003 = 31472106
139 + 31471967 = 31472106
167 + 31471939 = 31472106
173 + 31471933 = 31472106
199 + 31471907 = 31472106
223 + 31471883 = 31472106

Showing the first eight; more decompositions exist.
