Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39730, here are decompositions:

3 + 39727 = 39730
11 + 39719 = 39730
59 + 39671 = 39730
71 + 39659 = 39730
107 + 39623 = 39730
149 + 39581 = 39730
167 + 39563 = 39730
179 + 39551 = 39730

Showing the first eight; more decompositions exist.
