Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31570794, here are decompositions:

7 + 31570787 = 31570794
37 + 31570757 = 31570794
127 + 31570667 = 31570794
181 + 31570613 = 31570794
191 + 31570603 = 31570794
293 + 31570501 = 31570794
313 + 31570481 = 31570794
347 + 31570447 = 31570794

Showing the first eight; more decompositions exist.
