Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469658, here are decompositions:

5 + 31469653 = 31469658
29 + 31469629 = 31469658
37 + 31469621 = 31469658
71 + 31469587 = 31469658
79 + 31469579 = 31469658
89 + 31469569 = 31469658
97 + 31469561 = 31469658
127 + 31469531 = 31469658

Showing the first eight; more decompositions exist.
