Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39670, here are decompositions:

3 + 39667 = 39670
11 + 39659 = 39670
47 + 39623 = 39670
89 + 39581 = 39670
101 + 39569 = 39670
107 + 39563 = 39670
149 + 39521 = 39670
167 + 39503 = 39670

Showing the first eight; more decompositions exist.
