Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600500, here are decompositions:

7 + 31600493 = 31600500
47 + 31600453 = 31600500
53 + 31600447 = 31600500
59 + 31600441 = 31600500
79 + 31600421 = 31600500
167 + 31600333 = 31600500
181 + 31600319 = 31600500
193 + 31600307 = 31600500

Showing the first eight; more decompositions exist.
