Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31570364, here are decompositions:

61 + 31570303 = 31570364
73 + 31570291 = 31570364
103 + 31570261 = 31570364
193 + 31570171 = 31570364
223 + 31570141 = 31570364
277 + 31570087 = 31570364
283 + 31570081 = 31570364
307 + 31570057 = 31570364

Showing the first eight; more decompositions exist.
