Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31570536, here are decompositions:

17 + 31570519 = 31570536
29 + 31570507 = 31570536
37 + 31570499 = 31570536
89 + 31570447 = 31570536
139 + 31570397 = 31570536
157 + 31570379 = 31570536
163 + 31570373 = 31570536
199 + 31570337 = 31570536

Showing the first eight; more decompositions exist.
