Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66398, here are decompositions:

37 + 66361 = 66398
61 + 66337 = 66398
97 + 66301 = 66398
127 + 66271 = 66398
229 + 66169 = 66398
331 + 66067 = 66398
499 + 65899 = 66398
547 + 65851 = 66398

Showing the first eight; more decompositions exist.
