Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600012, here are decompositions:

11 + 31600001 = 31600012
53 + 31599959 = 31600012
71 + 31599941 = 31600012
83 + 31599929 = 31600012
239 + 31599773 = 31600012
251 + 31599761 = 31600012
359 + 31599653 = 31600012
383 + 31599629 = 31600012

Showing the first eight; more decompositions exist.
