Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524760, here are decompositions:

83 + 31524677 = 31524760
173 + 31524587 = 31524760
191 + 31524569 = 31524760
227 + 31524533 = 31524760
251 + 31524509 = 31524760
467 + 31524293 = 31524760
503 + 31524257 = 31524760
563 + 31524197 = 31524760

Showing the first eight; more decompositions exist.
