Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469742, here are decompositions:

11 + 31469731 = 31469742
19 + 31469723 = 31469742
53 + 31469689 = 31469742
71 + 31469671 = 31469742
89 + 31469653 = 31469742
113 + 31469629 = 31469742
163 + 31469579 = 31469742
173 + 31469569 = 31469742

Showing the first eight; more decompositions exist.
