Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469622, here are decompositions:

43 + 31469579 = 31469622
53 + 31469569 = 31469622
59 + 31469563 = 31469622
61 + 31469561 = 31469622
103 + 31469519 = 31469622
109 + 31469513 = 31469622
179 + 31469443 = 31469622
181 + 31469441 = 31469622

Showing the first eight; more decompositions exist.
