Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469286, here are decompositions:

7 + 31469279 = 31469286
47 + 31469239 = 31469286
89 + 31469197 = 31469286
109 + 31469177 = 31469286
293 + 31468993 = 31469286
367 + 31468919 = 31469286
383 + 31468903 = 31469286
463 + 31468823 = 31469286

Showing the first eight; more decompositions exist.
