Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524886, here are decompositions:

23 + 31524863 = 31524886
47 + 31524839 = 31524886
89 + 31524797 = 31524886
317 + 31524569 = 31524886
353 + 31524533 = 31524886
467 + 31524419 = 31524886
593 + 31524293 = 31524886
719 + 31524167 = 31524886

Showing the first eight; more decompositions exist.
