Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524838, here are decompositions:

29 + 31524809 = 31524838
41 + 31524797 = 31524838
47 + 31524791 = 31524838
71 + 31524767 = 31524838
197 + 31524641 = 31524838
251 + 31524587 = 31524838
269 + 31524569 = 31524838
419 + 31524419 = 31524838

Showing the first eight; more decompositions exist.
