Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573924, here are decompositions:

71 + 31573853 = 31573924
101 + 31573823 = 31573924
131 + 31573793 = 31573924
167 + 31573757 = 31573924
227 + 31573697 = 31573924
281 + 31573643 = 31573924
353 + 31573571 = 31573924
401 + 31573523 = 31573924

Showing the first eight; more decompositions exist.
