Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66458, here are decompositions:

97 + 66361 = 66458
157 + 66301 = 66458
349 + 66109 = 66458
421 + 66037 = 66458
577 + 65881 = 66458
607 + 65851 = 66458
619 + 65839 = 66458
631 + 65827 = 66458

Showing the first eight; more decompositions exist.
