Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499236, here are decompositions:

5 + 31499231 = 31499236
47 + 31499189 = 31499236
53 + 31499183 = 31499236
173 + 31499063 = 31499236
179 + 31499057 = 31499236
233 + 31499003 = 31499236
269 + 31498967 = 31499236
383 + 31498853 = 31499236

Showing the first eight; more decompositions exist.
