Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31570462, here are decompositions:

3 + 31570459 = 31570462
71 + 31570391 = 31570462
83 + 31570379 = 31570462
89 + 31570373 = 31570462
149 + 31570313 = 31570462
173 + 31570289 = 31570462
239 + 31570223 = 31570462
251 + 31570211 = 31570462

Showing the first eight; more decompositions exist.
