Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567892, here are decompositions:

43 + 31567849 = 31567892
73 + 31567819 = 31567892
79 + 31567813 = 31567892
151 + 31567741 = 31567892
163 + 31567729 = 31567892
193 + 31567699 = 31567892
199 + 31567693 = 31567892
211 + 31567681 = 31567892

Showing the first eight; more decompositions exist.
