Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525232, here are decompositions:

3 + 31525229 = 31525232
19 + 31525213 = 31525232
31 + 31525201 = 31525232
241 + 31524991 = 31525232
439 + 31524793 = 31525232
691 + 31524541 = 31525232
709 + 31524523 = 31525232
733 + 31524499 = 31525232

Showing the first eight; more decompositions exist.
