Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524710, here are decompositions:

37 + 31524673 = 31524710
67 + 31524643 = 31524710
103 + 31524607 = 31524710
193 + 31524517 = 31524710
211 + 31524499 = 31524710
241 + 31524469 = 31524710
307 + 31524403 = 31524710
367 + 31524343 = 31524710

Showing the first eight; more decompositions exist.
