Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468998, here are decompositions:

5 + 31468993 = 31468998
31 + 31468967 = 31468998
79 + 31468919 = 31468998
97 + 31468901 = 31468998
137 + 31468861 = 31468998
149 + 31468849 = 31468998
241 + 31468757 = 31468998
271 + 31468727 = 31468998

Showing the first eight; more decompositions exist.
