Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469248, here are decompositions:

71 + 31469177 = 31469248
179 + 31469069 = 31469248
281 + 31468967 = 31469248
347 + 31468901 = 31469248
491 + 31468757 = 31469248
521 + 31468727 = 31469248
617 + 31468631 = 31469248
659 + 31468589 = 31469248

Showing the first eight; more decompositions exist.
