Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600036, here are decompositions:

59 + 31599977 = 31600036
107 + 31599929 = 31600036
227 + 31599809 = 31600036
263 + 31599773 = 31600036
269 + 31599767 = 31600036
353 + 31599683 = 31600036
383 + 31599653 = 31600036
647 + 31599389 = 31600036

Showing the first eight; more decompositions exist.
