Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498794, here are decompositions:

31 + 31498763 = 31498794
53 + 31498741 = 31498794
137 + 31498657 = 31498794
277 + 31498517 = 31498794
281 + 31498513 = 31498794
331 + 31498463 = 31498794
367 + 31498427 = 31498794
373 + 31498421 = 31498794

Showing the first eight; more decompositions exist.
