Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66218, here are decompositions:

109 + 66109 = 66218
151 + 66067 = 66218
181 + 66037 = 66218
337 + 65881 = 66218
367 + 65851 = 66218
379 + 65839 = 66218
409 + 65809 = 66218
457 + 65761 = 66218

Showing the first eight; more decompositions exist.
