Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524988, here are decompositions:

149 + 31524839 = 31524988
179 + 31524809 = 31524988
191 + 31524797 = 31524988
197 + 31524791 = 31524988
311 + 31524677 = 31524988
347 + 31524641 = 31524988
401 + 31524587 = 31524988
419 + 31524569 = 31524988

Showing the first eight; more decompositions exist.
