Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17860, here are decompositions:

23 + 17837 = 17860
53 + 17807 = 17860
71 + 17789 = 17860
113 + 17747 = 17860
131 + 17729 = 17860
179 + 17681 = 17860
191 + 17669 = 17860
233 + 17627 = 17860

Showing the first eight; more decompositions exist.
