Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31570044, here are decompositions:

31 + 31570013 = 31570044
61 + 31569983 = 31570044
67 + 31569977 = 31570044
101 + 31569943 = 31570044
193 + 31569851 = 31570044
251 + 31569793 = 31570044
263 + 31569781 = 31570044
277 + 31569767 = 31570044

Showing the first eight; more decompositions exist.
