Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601794, here are decompositions:

11 + 31601783 = 31601794
71 + 31601723 = 31601794
83 + 31601711 = 31601794
227 + 31601567 = 31601794
281 + 31601513 = 31601794
383 + 31601411 = 31601794
401 + 31601393 = 31601794
743 + 31601051 = 31601794

Showing the first eight; more decompositions exist.
