Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495514, here are decompositions:

3 + 31495511 = 31495514
13 + 31495501 = 31495514
67 + 31495447 = 31495514
97 + 31495417 = 31495514
157 + 31495357 = 31495514
163 + 31495351 = 31495514
181 + 31495333 = 31495514
241 + 31495273 = 31495514

Showing the first eight; more decompositions exist.
