Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39812, here are decompositions:

13 + 39799 = 39812
43 + 39769 = 39812
79 + 39733 = 39812
103 + 39709 = 39812
109 + 39703 = 39812
181 + 39631 = 39812
193 + 39619 = 39812
271 + 39541 = 39812

Showing the first eight; more decompositions exist.
