Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499516, here are decompositions:

19 + 31499497 = 31499516
109 + 31499407 = 31499516
193 + 31499323 = 31499516
277 + 31499239 = 31499516
379 + 31499137 = 31499516
409 + 31499107 = 31499516
439 + 31499077 = 31499516
523 + 31498993 = 31499516

Showing the first eight; more decompositions exist.
