Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469598, here are decompositions:

11 + 31469587 = 31469598
19 + 31469579 = 31469598
29 + 31469569 = 31469598
37 + 31469561 = 31469598
67 + 31469531 = 31469598
71 + 31469527 = 31469598
79 + 31469519 = 31469598
131 + 31469467 = 31469598

Showing the first eight; more decompositions exist.
