Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573094, here are decompositions:

37 + 31573057 = 31573094
67 + 31573027 = 31573094
73 + 31573021 = 31573094
151 + 31572943 = 31573094
193 + 31572901 = 31573094
271 + 31572823 = 31573094
331 + 31572763 = 31573094
367 + 31572727 = 31573094

Showing the first eight; more decompositions exist.
