Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567236, here are decompositions:

5 + 31567231 = 31567236
17 + 31567219 = 31567236
23 + 31567213 = 31567236
79 + 31567157 = 31567236
83 + 31567153 = 31567236
149 + 31567087 = 31567236
193 + 31567043 = 31567236
257 + 31566979 = 31567236

Showing the first eight; more decompositions exist.
