Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524794, here are decompositions:

3 + 31524791 = 31524794
31 + 31524763 = 31524794
73 + 31524721 = 31524794
151 + 31524643 = 31524794
271 + 31524523 = 31524794
277 + 31524517 = 31524794
463 + 31524331 = 31524794
523 + 31524271 = 31524794

Showing the first eight; more decompositions exist.
