Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495374, here are decompositions:

7 + 31495367 = 31495374
13 + 31495361 = 31495374
17 + 31495357 = 31495374
23 + 31495351 = 31495374
41 + 31495333 = 31495374
101 + 31495273 = 31495374
227 + 31495147 = 31495374
257 + 31495117 = 31495374

Showing the first eight; more decompositions exist.
