Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498934, here are decompositions:

3 + 31498931 = 31498934
37 + 31498897 = 31498934
67 + 31498867 = 31498934
97 + 31498837 = 31498934
193 + 31498741 = 31498934
277 + 31498657 = 31498934
421 + 31498513 = 31498934
463 + 31498471 = 31498934

Showing the first eight; more decompositions exist.
