Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31481704, here are decompositions:

3 + 31481701 = 31481704
83 + 31481621 = 31481704
113 + 31481591 = 31481704
173 + 31481531 = 31481704
197 + 31481507 = 31481704
227 + 31481477 = 31481704
251 + 31481453 = 31481704
311 + 31481393 = 31481704

Showing the first eight; more decompositions exist.
