Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574926, here are decompositions:

113 + 31574813 = 31574926
179 + 31574747 = 31574926
233 + 31574693 = 31574926
239 + 31574687 = 31574926
269 + 31574657 = 31574926
419 + 31574507 = 31574926
557 + 31574369 = 31574926
563 + 31574363 = 31574926

Showing the first eight; more decompositions exist.
