Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524784, here are decompositions:

17 + 31524767 = 31524784
107 + 31524677 = 31524784
197 + 31524587 = 31524784
251 + 31524533 = 31524784
491 + 31524293 = 31524784
587 + 31524197 = 31524784
617 + 31524167 = 31524784
677 + 31524107 = 31524784

Showing the first eight; more decompositions exist.
