Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31572094, here are decompositions:

11 + 31572083 = 31572094
53 + 31572041 = 31572094
101 + 31571993 = 31572094
131 + 31571963 = 31572094
137 + 31571957 = 31572094
227 + 31571867 = 31572094
317 + 31571777 = 31572094
347 + 31571747 = 31572094

Showing the first eight; more decompositions exist.
