Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31570684, here are decompositions:

11 + 31570673 = 31570684
17 + 31570667 = 31570684
71 + 31570613 = 31570684
107 + 31570577 = 31570684
293 + 31570391 = 31570684
311 + 31570373 = 31570684
347 + 31570337 = 31570684
461 + 31570223 = 31570684

Showing the first eight; more decompositions exist.
