Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524808, here are decompositions:

11 + 31524797 = 31524808
17 + 31524791 = 31524808
41 + 31524767 = 31524808
131 + 31524677 = 31524808
167 + 31524641 = 31524808
239 + 31524569 = 31524808
389 + 31524419 = 31524808
641 + 31524167 = 31524808

Showing the first eight; more decompositions exist.
