Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42554, here are decompositions:

67 + 42487 = 42554
97 + 42457 = 42554
103 + 42451 = 42554
151 + 42403 = 42554
157 + 42397 = 42554
163 + 42391 = 42554
181 + 42373 = 42554
223 + 42331 = 42554

Showing the first eight; more decompositions exist.
