Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524826, here are decompositions:

17 + 31524809 = 31524826
29 + 31524797 = 31524826
59 + 31524767 = 31524826
149 + 31524677 = 31524826
239 + 31524587 = 31524826
257 + 31524569 = 31524826
293 + 31524533 = 31524826
317 + 31524509 = 31524826

Showing the first eight; more decompositions exist.
