Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541794, here are decompositions:

101 + 31541693 = 31541794
197 + 31541597 = 31541794
311 + 31541483 = 31541794
653 + 31541141 = 31541794
677 + 31541117 = 31541794
743 + 31541051 = 31541794
773 + 31541021 = 31541794
971 + 31540823 = 31541794

Showing the first eight; more decompositions exist.
