Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495416, here are decompositions:

13 + 31495403 = 31495416
59 + 31495357 = 31495416
83 + 31495333 = 31495416
229 + 31495187 = 31495416
263 + 31495153 = 31495416
269 + 31495147 = 31495416
307 + 31495109 = 31495416
353 + 31495063 = 31495416

Showing the first eight; more decompositions exist.
