Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574994, here are decompositions:

5 + 31574989 = 31574994
13 + 31574981 = 31574994
67 + 31574927 = 31574994
83 + 31574911 = 31574994
103 + 31574891 = 31574994
107 + 31574887 = 31574994
131 + 31574863 = 31574994
173 + 31574821 = 31574994

Showing the first eight; more decompositions exist.
