Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567012, here are decompositions:

101 + 31566911 = 31567012
149 + 31566863 = 31567012
173 + 31566839 = 31567012
263 + 31566749 = 31567012
353 + 31566659 = 31567012
401 + 31566611 = 31567012
563 + 31566449 = 31567012
569 + 31566443 = 31567012

Showing the first eight; more decompositions exist.
