Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39800, here are decompositions:

31 + 39769 = 39800
67 + 39733 = 39800
73 + 39727 = 39800
97 + 39703 = 39800
181 + 39619 = 39800
193 + 39607 = 39800
349 + 39451 = 39800
433 + 39367 = 39800

Showing the first eight; more decompositions exist.
