Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498036, here are decompositions:

29 + 31498007 = 31498036
107 + 31497929 = 31498036
173 + 31497863 = 31498036
233 + 31497803 = 31498036
239 + 31497797 = 31498036
263 + 31497773 = 31498036
467 + 31497569 = 31498036
509 + 31497527 = 31498036

Showing the first eight; more decompositions exist.
