Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164860, here are decompositions:

23 + 164837 = 164860
29 + 164831 = 164860
71 + 164789 = 164860
89 + 164771 = 164860
131 + 164729 = 164860
197 + 164663 = 164860
233 + 164627 = 164860
239 + 164621 = 164860

Showing the first eight; more decompositions exist.
