Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469086, here are decompositions:

17 + 31469069 = 31469086
53 + 31469033 = 31469086
59 + 31469027 = 31469086
167 + 31468919 = 31469086
263 + 31468823 = 31469086
293 + 31468793 = 31469086
359 + 31468727 = 31469086
419 + 31468667 = 31469086

Showing the first eight; more decompositions exist.
