Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468286, here are decompositions:

43 + 31468243 = 31468286
127 + 31468159 = 31468286
139 + 31468147 = 31468286
337 + 31467949 = 31468286
349 + 31467937 = 31468286
433 + 31467853 = 31468286
439 + 31467847 = 31468286
457 + 31467829 = 31468286

Showing the first eight; more decompositions exist.
