Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42308, here are decompositions:

127 + 42181 = 42308
139 + 42169 = 42308
151 + 42157 = 42308
349 + 41959 = 42308
367 + 41941 = 42308
397 + 41911 = 42308
421 + 41887 = 42308
457 + 41851 = 42308

Showing the first eight; more decompositions exist.
