Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31570626, here are decompositions:

7 + 31570619 = 31570626
13 + 31570613 = 31570626
23 + 31570603 = 31570626
107 + 31570519 = 31570626
127 + 31570499 = 31570626
167 + 31570459 = 31570626
179 + 31570447 = 31570626
229 + 31570397 = 31570626

Showing the first eight; more decompositions exist.
