Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524790, here are decompositions:

23 + 31524767 = 31524790
113 + 31524677 = 31524790
149 + 31524641 = 31524790
257 + 31524533 = 31524790
281 + 31524509 = 31524790
593 + 31524197 = 31524790
683 + 31524107 = 31524790
743 + 31524047 = 31524790

Showing the first eight; more decompositions exist.
