Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469422, here are decompositions:

11 + 31469411 = 31469422
353 + 31469069 = 31469422
389 + 31469033 = 31469422
503 + 31468919 = 31469422
521 + 31468901 = 31469422
599 + 31468823 = 31469422
863 + 31468559 = 31469422
911 + 31468511 = 31469422

Showing the first eight; more decompositions exist.
