Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472074, here are decompositions:

5 + 31472069 = 31472074
71 + 31472003 = 31472074
83 + 31471991 = 31472074
107 + 31471967 = 31472074
167 + 31471907 = 31472074
173 + 31471901 = 31472074
191 + 31471883 = 31472074
251 + 31471823 = 31472074

Showing the first eight; more decompositions exist.
