Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469008, here are decompositions:

41 + 31468967 = 31469008
89 + 31468919 = 31469008
107 + 31468901 = 31469008
251 + 31468757 = 31469008
281 + 31468727 = 31469008
419 + 31468589 = 31469008
449 + 31468559 = 31469008
479 + 31468529 = 31469008

Showing the first eight; more decompositions exist.
