Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567002, here are decompositions:

23 + 31566979 = 31567002
29 + 31566973 = 31567002
83 + 31566919 = 31567002
101 + 31566901 = 31567002
139 + 31566863 = 31567002
163 + 31566839 = 31567002
199 + 31566803 = 31567002
239 + 31566763 = 31567002

Showing the first eight; more decompositions exist.
