Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574794, here are decompositions:

47 + 31574747 = 31574794
71 + 31574723 = 31574794
101 + 31574693 = 31574794
107 + 31574687 = 31574794
113 + 31574681 = 31574794
137 + 31574657 = 31574794
263 + 31574531 = 31574794
431 + 31574363 = 31574794

Showing the first eight; more decompositions exist.
