Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18740, here are decompositions:

61 + 18679 = 18740
79 + 18661 = 18740
103 + 18637 = 18740
157 + 18583 = 18740
199 + 18541 = 18740
223 + 18517 = 18740
283 + 18457 = 18740
307 + 18433 = 18740

Showing the first eight; more decompositions exist.
