Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468202, here are decompositions:

43 + 31468159 = 31468202
349 + 31467853 = 31468202
373 + 31467829 = 31468202
439 + 31467763 = 31468202
613 + 31467589 = 31468202
631 + 31467571 = 31468202
643 + 31467559 = 31468202
769 + 31467433 = 31468202

Showing the first eight; more decompositions exist.
