Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498046, here are decompositions:

3 + 31498043 = 31498046
7 + 31498039 = 31498046
37 + 31498009 = 31498046
43 + 31498003 = 31498046
67 + 31497979 = 31498046
163 + 31497883 = 31498046
367 + 31497679 = 31498046
373 + 31497673 = 31498046

Showing the first eight; more decompositions exist.
