Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39668, here are decompositions:

37 + 39631 = 39668
61 + 39607 = 39668
127 + 39541 = 39668
157 + 39511 = 39668
229 + 39439 = 39668
271 + 39397 = 39668
367 + 39301 = 39668
439 + 39229 = 39668

Showing the first eight; more decompositions exist.
