Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567222, here are decompositions:

3 + 31567219 = 31567222
131 + 31567091 = 31567222
173 + 31567049 = 31567222
179 + 31567043 = 31567222
311 + 31566911 = 31567222
359 + 31566863 = 31567222
383 + 31566839 = 31567222
419 + 31566803 = 31567222

Showing the first eight; more decompositions exist.
