Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469218, here are decompositions:

41 + 31469177 = 31469218
149 + 31469069 = 31469218
191 + 31469027 = 31469218
251 + 31468967 = 31469218
317 + 31468901 = 31469218
461 + 31468757 = 31469218
491 + 31468727 = 31469218
587 + 31468631 = 31469218

Showing the first eight; more decompositions exist.
