Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468798, here are decompositions:

5 + 31468793 = 31468798
41 + 31468757 = 31468798
71 + 31468727 = 31468798
131 + 31468667 = 31468798
167 + 31468631 = 31468798
227 + 31468571 = 31468798
239 + 31468559 = 31468798
269 + 31468529 = 31468798

Showing the first eight; more decompositions exist.
