Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574670, here are decompositions:

13 + 31574657 = 31574670
31 + 31574639 = 31574670
107 + 31574563 = 31574670
139 + 31574531 = 31574670
163 + 31574507 = 31574670
173 + 31574497 = 31574670
181 + 31574489 = 31574670
191 + 31574479 = 31574670

Showing the first eight; more decompositions exist.
