Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66488, here are decompositions:

31 + 66457 = 66488
127 + 66361 = 66488
151 + 66337 = 66488
379 + 66109 = 66488
421 + 66067 = 66488
607 + 65881 = 66488
661 + 65827 = 66488
727 + 65761 = 66488

Showing the first eight; more decompositions exist.
