Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17826, here are decompositions:

19 + 17807 = 17826
37 + 17789 = 17826
43 + 17783 = 17826
79 + 17747 = 17826
89 + 17737 = 17826
97 + 17729 = 17826
113 + 17713 = 17826
157 + 17669 = 17826

Showing the first eight; more decompositions exist.
