Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495484, here are decompositions:

3 + 31495481 = 31495484
37 + 31495447 = 31495484
61 + 31495423 = 31495484
67 + 31495417 = 31495484
127 + 31495357 = 31495484
151 + 31495333 = 31495484
211 + 31495273 = 31495484
271 + 31495213 = 31495484

Showing the first eight; more decompositions exist.
