Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31570132, here are decompositions:

29 + 31570103 = 31570132
89 + 31570043 = 31570132
149 + 31569983 = 31570132
179 + 31569953 = 31570132
281 + 31569851 = 31570132
431 + 31569701 = 31570132
443 + 31569689 = 31570132
491 + 31569641 = 31570132

Showing the first eight; more decompositions exist.
