Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495476, here are decompositions:

7 + 31495469 = 31495476
13 + 31495463 = 31495476
29 + 31495447 = 31495476
53 + 31495423 = 31495476
59 + 31495417 = 31495476
73 + 31495403 = 31495476
109 + 31495367 = 31495476
263 + 31495213 = 31495476

Showing the first eight; more decompositions exist.
