Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524708, here are decompositions:

31 + 31524677 = 31524708
67 + 31524641 = 31524708
101 + 31524607 = 31524708
139 + 31524569 = 31524708
167 + 31524541 = 31524708
191 + 31524517 = 31524708
199 + 31524509 = 31524708
239 + 31524469 = 31524708

Showing the first eight; more decompositions exist.
