Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39784, here are decompositions:

5 + 39779 = 39784
23 + 39761 = 39784
113 + 39671 = 39784
233 + 39551 = 39784
263 + 39521 = 39784
281 + 39503 = 39784
401 + 39383 = 39784
443 + 39341 = 39784

Showing the first eight; more decompositions exist.
