Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495694, here are decompositions:

3 + 31495691 = 31495694
31 + 31495663 = 31495694
37 + 31495657 = 31495694
103 + 31495591 = 31495694
193 + 31495501 = 31495694
271 + 31495423 = 31495694
277 + 31495417 = 31495694
337 + 31495357 = 31495694

Showing the first eight; more decompositions exist.
