Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529232, here are decompositions:

13 + 31529219 = 31529232
19 + 31529213 = 31529232
83 + 31529149 = 31529232
151 + 31529081 = 31529232
179 + 31529053 = 31529232
239 + 31528993 = 31529232
263 + 31528969 = 31529232
379 + 31528853 = 31529232

Showing the first eight; more decompositions exist.
