Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66404, here are decompositions:

31 + 66373 = 66404
43 + 66361 = 66404
61 + 66343 = 66404
67 + 66337 = 66404
103 + 66301 = 66404
337 + 66067 = 66404
367 + 66037 = 66404
421 + 65983 = 66404

Showing the first eight; more decompositions exist.
