Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567860, here are decompositions:

11 + 31567849 = 31567860
41 + 31567819 = 31567860
47 + 31567813 = 31567860
131 + 31567729 = 31567860
151 + 31567709 = 31567860
167 + 31567693 = 31567860
173 + 31567687 = 31567860
179 + 31567681 = 31567860

Showing the first eight; more decompositions exist.
