Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573896, here are decompositions:

37 + 31573859 = 31573896
43 + 31573853 = 31573896
73 + 31573823 = 31573896
103 + 31573793 = 31573896
139 + 31573757 = 31573896
149 + 31573747 = 31573896
199 + 31573697 = 31573896
257 + 31573639 = 31573896

Showing the first eight; more decompositions exist.
