Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39700, here are decompositions:

29 + 39671 = 39700
41 + 39659 = 39700
131 + 39569 = 39700
137 + 39563 = 39700
149 + 39551 = 39700
179 + 39521 = 39700
191 + 39509 = 39700
197 + 39503 = 39700

Showing the first eight; more decompositions exist.
