Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469586, here are decompositions:

7 + 31469579 = 31469586
17 + 31469569 = 31469586
23 + 31469563 = 31469586
59 + 31469527 = 31469586
67 + 31469519 = 31469586
73 + 31469513 = 31469586
139 + 31469447 = 31469586
163 + 31469423 = 31469586

Showing the first eight; more decompositions exist.
