Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 181484, here are decompositions:

97 + 181387 = 181484
181 + 181303 = 181484
211 + 181273 = 181484
241 + 181243 = 181484
271 + 181213 = 181484
283 + 181201 = 181484
397 + 181087 = 181484
421 + 181063 = 181484

Showing the first eight; more decompositions exist.
