Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66698, here are decompositions:

97 + 66601 = 66698
127 + 66571 = 66698
157 + 66541 = 66698
199 + 66499 = 66698
241 + 66457 = 66698
337 + 66361 = 66698
397 + 66301 = 66698
631 + 66067 = 66698

Showing the first eight; more decompositions exist.
