Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524772, here are decompositions:

5 + 31524767 = 31524772
131 + 31524641 = 31524772
239 + 31524533 = 31524772
263 + 31524509 = 31524772
353 + 31524419 = 31524772
479 + 31524293 = 31524772
761 + 31524011 = 31524772
971 + 31523801 = 31524772

Showing the first eight; more decompositions exist.
