Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 186506, here are decompositions:

37 + 186469 = 186506
109 + 186397 = 186506
127 + 186379 = 186506
163 + 186343 = 186506
223 + 186283 = 186506
277 + 186229 = 186506
349 + 186157 = 186506
409 + 186097 = 186506

Showing the first eight; more decompositions exist.
