Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66446, here are decompositions:

43 + 66403 = 66446
73 + 66373 = 66446
103 + 66343 = 66446
109 + 66337 = 66446
277 + 66169 = 66446
337 + 66109 = 66446
379 + 66067 = 66446
409 + 66037 = 66446

Showing the first eight; more decompositions exist.
