Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469992, here are decompositions:

3 + 31469989 = 31469992
5 + 31469987 = 31469992
89 + 31469903 = 31469992
131 + 31469861 = 31469992
179 + 31469813 = 31469992
251 + 31469741 = 31469992
269 + 31469723 = 31469992
431 + 31469561 = 31469992

Showing the first eight; more decompositions exist.
