Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469738, here are decompositions:

7 + 31469731 = 31469738
67 + 31469671 = 31469738
109 + 31469629 = 31469738
151 + 31469587 = 31469738
211 + 31469527 = 31469738
271 + 31469467 = 31469738
331 + 31469407 = 31469738
439 + 31469299 = 31469738

Showing the first eight; more decompositions exist.
