Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498074, here are decompositions:

5 + 31498069 = 31498074
31 + 31498043 = 31498074
67 + 31498007 = 31498074
71 + 31498003 = 31498074
191 + 31497883 = 31498074
211 + 31497863 = 31498074
271 + 31497803 = 31498074
277 + 31497797 = 31498074

Showing the first eight; more decompositions exist.
