Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31481734, here are decompositions:

3 + 31481731 = 31481734
17 + 31481717 = 31481734
23 + 31481711 = 31481734
113 + 31481621 = 31481734
191 + 31481543 = 31481734
227 + 31481507 = 31481734
257 + 31481477 = 31481734
281 + 31481453 = 31481734

Showing the first eight; more decompositions exist.
