Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31570022, here are decompositions:

79 + 31569943 = 31570022
139 + 31569883 = 31570022
163 + 31569859 = 31570022
193 + 31569829 = 31570022
229 + 31569793 = 31570022
241 + 31569781 = 31570022
271 + 31569751 = 31570022
313 + 31569709 = 31570022

Showing the first eight; more decompositions exist.
