Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472152, here are decompositions:

3 + 31472149 = 31472152
29 + 31472123 = 31472152
83 + 31472069 = 31472152
149 + 31472003 = 31472152
251 + 31471901 = 31472152
269 + 31471883 = 31472152
353 + 31471799 = 31472152
389 + 31471763 = 31472152

Showing the first eight; more decompositions exist.
