Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17830, here are decompositions:

3 + 17827 = 17830
23 + 17807 = 17830
41 + 17789 = 17830
47 + 17783 = 17830
83 + 17747 = 17830
101 + 17729 = 17830
149 + 17681 = 17830
173 + 17657 = 17830

Showing the first eight; more decompositions exist.
