Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31570374, here are decompositions:

37 + 31570337 = 31570374
61 + 31570313 = 31570374
71 + 31570303 = 31570374
83 + 31570291 = 31570374
113 + 31570261 = 31570374
151 + 31570223 = 31570374
163 + 31570211 = 31570374
181 + 31570193 = 31570374

Showing the first eight; more decompositions exist.
