Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498066, here are decompositions:

23 + 31498043 = 31498066
59 + 31498007 = 31498066
137 + 31497929 = 31498066
239 + 31497827 = 31498066
263 + 31497803 = 31498066
269 + 31497797 = 31498066
293 + 31497773 = 31498066
359 + 31497707 = 31498066

Showing the first eight; more decompositions exist.
