Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469284, here are decompositions:

5 + 31469279 = 31469284
107 + 31469177 = 31469284
251 + 31469033 = 31469284
257 + 31469027 = 31469284
317 + 31468967 = 31469284
383 + 31468901 = 31469284
461 + 31468823 = 31469284
491 + 31468793 = 31469284

Showing the first eight; more decompositions exist.
