Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529248, here are decompositions:

5 + 31529243 = 31529248
29 + 31529219 = 31529248
167 + 31529081 = 31529248
251 + 31528997 = 31529248
281 + 31528967 = 31529248
701 + 31528547 = 31529248
797 + 31528451 = 31529248
911 + 31528337 = 31529248

Showing the first eight; more decompositions exist.
