Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472032, here are decompositions:

3 + 31472029 = 31472032
29 + 31472003 = 31472032
41 + 31471991 = 31472032
131 + 31471901 = 31472032
149 + 31471883 = 31472032
233 + 31471799 = 31472032
269 + 31471763 = 31472032
509 + 31471523 = 31472032

Showing the first eight; more decompositions exist.
