Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31570060, here are decompositions:

3 + 31570057 = 31570060
17 + 31570043 = 31570060
47 + 31570013 = 31570060
83 + 31569977 = 31570060
107 + 31569953 = 31570060
293 + 31569767 = 31570060
359 + 31569701 = 31570060
419 + 31569641 = 31570060

Showing the first eight; more decompositions exist.
