Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524958, here are decompositions:

149 + 31524809 = 31524958
167 + 31524791 = 31524958
191 + 31524767 = 31524958
281 + 31524677 = 31524958
317 + 31524641 = 31524958
389 + 31524569 = 31524958
449 + 31524509 = 31524958
701 + 31524257 = 31524958

Showing the first eight; more decompositions exist.
