Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31500094, here are decompositions:

11 + 31500083 = 31500094
47 + 31500047 = 31500094
71 + 31500023 = 31500094
173 + 31499921 = 31500094
251 + 31499843 = 31500094
383 + 31499711 = 31500094
557 + 31499537 = 31500094
683 + 31499411 = 31500094

Showing the first eight; more decompositions exist.
