Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 181496, here are decompositions:

37 + 181459 = 181496
97 + 181399 = 181496
109 + 181387 = 181496
193 + 181303 = 181496
199 + 181297 = 181496
223 + 181273 = 181496
277 + 181219 = 181496
283 + 181213 = 181496

Showing the first eight; more decompositions exist.
