Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18758, here are decompositions:

67 + 18691 = 18758
79 + 18679 = 18758
97 + 18661 = 18758
241 + 18517 = 18758
277 + 18481 = 18758
307 + 18451 = 18758
331 + 18427 = 18758
379 + 18379 = 18758

Showing the first eight; more decompositions exist.
