Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601094, here are decompositions:

11 + 31601083 = 31601094
17 + 31601077 = 31601094
43 + 31601051 = 31601094
53 + 31601041 = 31601094
71 + 31601023 = 31601094
101 + 31600993 = 31601094
137 + 31600957 = 31601094
211 + 31600883 = 31601094

Showing the first eight; more decompositions exist.
