Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 183664, here are decompositions:

3 + 183661 = 183664
53 + 183611 = 183664
71 + 183593 = 183664
83 + 183581 = 183664
137 + 183527 = 183664
167 + 183497 = 183664
191 + 183473 = 183664
227 + 183437 = 183664

Showing the first eight; more decompositions exist.
