Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468898, here are decompositions:

37 + 31468861 = 31468898
199 + 31468699 = 31468898
499 + 31468399 = 31468898
739 + 31468159 = 31468898
751 + 31468147 = 31468898
1051 + 31467847 = 31468898
1069 + 31467829 = 31468898
1087 + 31467811 = 31468898

Showing the first eight; more decompositions exist.
