Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498516, here are decompositions:

3 + 31498513 = 31498516
17 + 31498499 = 31498516
47 + 31498469 = 31498516
53 + 31498463 = 31498516
89 + 31498427 = 31498516
149 + 31498367 = 31498516
167 + 31498349 = 31498516
173 + 31498343 = 31498516

Showing the first eight; more decompositions exist.
