Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39658, here are decompositions:

89 + 39569 = 39658
107 + 39551 = 39658
137 + 39521 = 39658
149 + 39509 = 39658
197 + 39461 = 39658
239 + 39419 = 39658
317 + 39341 = 39658
419 + 39239 = 39658

Showing the first eight; more decompositions exist.
