Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 472142, here are decompositions:

3 + 472139 = 472142
19 + 472123 = 472142
31 + 472111 = 472142
79 + 472063 = 472142
193 + 471949 = 472142
199 + 471943 = 472142
211 + 471931 = 472142
241 + 471901 = 472142

Showing the first eight; more decompositions exist.
