Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42272, here are decompositions:

79 + 42193 = 42272
103 + 42169 = 42272
199 + 42073 = 42272
211 + 42061 = 42272
229 + 42043 = 42272
313 + 41959 = 42272
331 + 41941 = 42272
379 + 41893 = 42272

Showing the first eight; more decompositions exist.
