Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66416, here are decompositions:

3 + 66413 = 66416
13 + 66403 = 66416
43 + 66373 = 66416
73 + 66343 = 66416
79 + 66337 = 66416
307 + 66109 = 66416
313 + 66103 = 66416
349 + 66067 = 66416

Showing the first eight; more decompositions exist.
