Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468442, here are decompositions:

43 + 31468399 = 31468442
73 + 31468369 = 31468442
199 + 31468243 = 31468442
211 + 31468231 = 31468442
241 + 31468201 = 31468442
283 + 31468159 = 31468442
613 + 31467829 = 31468442
631 + 31467811 = 31468442

Showing the first eight; more decompositions exist.
