Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66506, here are decompositions:

7 + 66499 = 66506
43 + 66463 = 66506
103 + 66403 = 66506
163 + 66343 = 66506
337 + 66169 = 66506
397 + 66109 = 66506
439 + 66067 = 66506
523 + 65983 = 66506

Showing the first eight; more decompositions exist.
