Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31570674, here are decompositions:

7 + 31570667 = 31570674
61 + 31570613 = 31570674
71 + 31570603 = 31570674
97 + 31570577 = 31570674
167 + 31570507 = 31570674
173 + 31570501 = 31570674
193 + 31570481 = 31570674
227 + 31570447 = 31570674

Showing the first eight; more decompositions exist.
