Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495714, here are decompositions:

23 + 31495691 = 31495714
53 + 31495661 = 31495714
113 + 31495601 = 31495714
191 + 31495523 = 31495714
197 + 31495517 = 31495714
233 + 31495481 = 31495714
251 + 31495463 = 31495714
311 + 31495403 = 31495714

Showing the first eight; more decompositions exist.
