Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524892, here are decompositions:

29 + 31524863 = 31524892
53 + 31524839 = 31524892
83 + 31524809 = 31524892
101 + 31524791 = 31524892
251 + 31524641 = 31524892
359 + 31524533 = 31524892
383 + 31524509 = 31524892
599 + 31524293 = 31524892

Showing the first eight; more decompositions exist.
