Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469998, here are decompositions:

11 + 31469987 = 31469998
137 + 31469861 = 31469998
149 + 31469849 = 31469998
257 + 31469741 = 31469998
419 + 31469579 = 31469998
467 + 31469531 = 31469998
479 + 31469519 = 31469998
557 + 31469441 = 31469998

Showing the first eight; more decompositions exist.
