Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573876, here are decompositions:

17 + 31573859 = 31573876
23 + 31573853 = 31573876
29 + 31573847 = 31573876
53 + 31573823 = 31573876
83 + 31573793 = 31573876
179 + 31573697 = 31573876
197 + 31573679 = 31573876
233 + 31573643 = 31573876

Showing the first eight; more decompositions exist.
