Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31570074, here are decompositions:

17 + 31570057 = 31570074
31 + 31570043 = 31570074
61 + 31570013 = 31570074
97 + 31569977 = 31570074
131 + 31569943 = 31570074
191 + 31569883 = 31570074
223 + 31569851 = 31570074
281 + 31569793 = 31570074

Showing the first eight; more decompositions exist.
