Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469688, here are decompositions:

17 + 31469671 = 31469688
59 + 31469629 = 31469688
67 + 31469621 = 31469688
101 + 31469587 = 31469688
109 + 31469579 = 31469688
127 + 31469561 = 31469688
157 + 31469531 = 31469688
241 + 31469447 = 31469688

Showing the first eight; more decompositions exist.
