Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472932, here are decompositions:

3 + 31472929 = 31472932
5 + 31472927 = 31472932
41 + 31472891 = 31472932
53 + 31472879 = 31472932
83 + 31472849 = 31472932
233 + 31472699 = 31472932
263 + 31472669 = 31472932
269 + 31472663 = 31472932

Showing the first eight; more decompositions exist.
