Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17804, here are decompositions:

13 + 17791 = 17804
43 + 17761 = 17804
67 + 17737 = 17804
97 + 17707 = 17804
181 + 17623 = 17804
223 + 17581 = 17804
307 + 17497 = 17804
313 + 17491 = 17804

Showing the first eight; more decompositions exist.
