Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469892, here are decompositions:

31 + 31469861 = 31469892
43 + 31469849 = 31469892
79 + 31469813 = 31469892
109 + 31469783 = 31469892
131 + 31469761 = 31469892
151 + 31469741 = 31469892
239 + 31469653 = 31469892
263 + 31469629 = 31469892

Showing the first eight; more decompositions exist.
