Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468568, here are decompositions:

97 + 31468471 = 31468568
199 + 31468369 = 31468568
337 + 31468231 = 31468568
367 + 31468201 = 31468568
409 + 31468159 = 31468568
421 + 31468147 = 31468568
541 + 31468027 = 31468568
601 + 31467967 = 31468568

Showing the first eight; more decompositions exist.
