Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66438, here are decompositions:

7 + 66431 = 66438
61 + 66377 = 66438
79 + 66359 = 66438
101 + 66337 = 66438
137 + 66301 = 66438
167 + 66271 = 66438
199 + 66239 = 66438
269 + 66169 = 66438

Showing the first eight; more decompositions exist.
