Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468424, here are decompositions:

181 + 31468243 = 31468424
193 + 31468231 = 31468424
223 + 31468201 = 31468424
277 + 31468147 = 31468424
397 + 31468027 = 31468424
457 + 31467967 = 31468424
487 + 31467937 = 31468424
571 + 31467853 = 31468424

Showing the first eight; more decompositions exist.
