Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495006, here are decompositions:

3 + 31495003 = 31495006
83 + 31494923 = 31495006
197 + 31494809 = 31495006
239 + 31494767 = 31495006
269 + 31494737 = 31495006
293 + 31494713 = 31495006
317 + 31494689 = 31495006
503 + 31494503 = 31495006

Showing the first eight; more decompositions exist.
