Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31570746, here are decompositions:

37 + 31570709 = 31570746
73 + 31570673 = 31570746
79 + 31570667 = 31570746
127 + 31570619 = 31570746
227 + 31570519 = 31570746
239 + 31570507 = 31570746
349 + 31570397 = 31570746
367 + 31570379 = 31570746

Showing the first eight; more decompositions exist.
