Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495708, here are decompositions:

17 + 31495691 = 31495708
47 + 31495661 = 31495708
107 + 31495601 = 31495708
191 + 31495517 = 31495708
197 + 31495511 = 31495708
227 + 31495481 = 31495708
239 + 31495469 = 31495708
347 + 31495361 = 31495708

Showing the first eight; more decompositions exist.
