Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468822, here are decompositions:

29 + 31468793 = 31468822
191 + 31468631 = 31468822
233 + 31468589 = 31468822
251 + 31468571 = 31468822
263 + 31468559 = 31468822
269 + 31468553 = 31468822
293 + 31468529 = 31468822
311 + 31468511 = 31468822

Showing the first eight; more decompositions exist.
