Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567862, here are decompositions:

3 + 31567859 = 31567862
13 + 31567849 = 31567862
43 + 31567819 = 31567862
163 + 31567699 = 31567862
181 + 31567681 = 31567862
241 + 31567621 = 31567862
349 + 31567513 = 31567862
433 + 31567429 = 31567862

Showing the first eight; more decompositions exist.
