Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524738, here are decompositions:

17 + 31524721 = 31524738
61 + 31524677 = 31524738
97 + 31524641 = 31524738
131 + 31524607 = 31524738
151 + 31524587 = 31524738
197 + 31524541 = 31524738
229 + 31524509 = 31524738
239 + 31524499 = 31524738

Showing the first eight; more decompositions exist.
