Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469766, here are decompositions:

5 + 31469761 = 31469766
43 + 31469723 = 31469766
113 + 31469653 = 31469766
137 + 31469629 = 31469766
179 + 31469587 = 31469766
197 + 31469569 = 31469766
239 + 31469527 = 31469766
359 + 31469407 = 31469766

Showing the first eight; more decompositions exist.
