Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468196, here are decompositions:

37 + 31468159 = 31468196
229 + 31467967 = 31468196
349 + 31467847 = 31468196
367 + 31467829 = 31468196
433 + 31467763 = 31468196
607 + 31467589 = 31468196
829 + 31467367 = 31468196
937 + 31467259 = 31468196

Showing the first eight; more decompositions exist.
