Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524702, here are decompositions:

29 + 31524673 = 31524702
59 + 31524643 = 31524702
61 + 31524641 = 31524702
179 + 31524523 = 31524702
193 + 31524509 = 31524702
233 + 31524469 = 31524702
283 + 31524419 = 31524702
359 + 31524343 = 31524702

Showing the first eight; more decompositions exist.
