Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42548, here are decompositions:

61 + 42487 = 42548
97 + 42451 = 42548
139 + 42409 = 42548
151 + 42397 = 42548
157 + 42391 = 42548
199 + 42349 = 42548
211 + 42337 = 42548
241 + 42307 = 42548

Showing the first eight; more decompositions exist.
