Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17684, here are decompositions:

3 + 17681 = 17684
61 + 17623 = 17684
103 + 17581 = 17684
193 + 17491 = 17684
241 + 17443 = 17684
283 + 17401 = 17684
307 + 17377 = 17684
367 + 17317 = 17684

Showing the first eight; more decompositions exist.
