Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499254, here are decompositions:

23 + 31499231 = 31499254
71 + 31499183 = 31499254
191 + 31499063 = 31499254
197 + 31499057 = 31499254
233 + 31499021 = 31499254
251 + 31499003 = 31499254
263 + 31498991 = 31499254
401 + 31498853 = 31499254

Showing the first eight; more decompositions exist.
