Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39770, here are decompositions:

37 + 39733 = 39770
43 + 39727 = 39770
61 + 39709 = 39770
67 + 39703 = 39770
103 + 39667 = 39770
139 + 39631 = 39770
151 + 39619 = 39770
163 + 39607 = 39770

Showing the first eight; more decompositions exist.
