Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31570094, here are decompositions:

7 + 31570087 = 31570094
13 + 31570081 = 31570094
37 + 31570057 = 31570094
151 + 31569943 = 31570094
211 + 31569883 = 31570094
313 + 31569781 = 31570094
331 + 31569763 = 31570094
613 + 31569481 = 31570094

Showing the first eight; more decompositions exist.
