Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18710, here are decompositions:

19 + 18691 = 18710
31 + 18679 = 18710
73 + 18637 = 18710
127 + 18583 = 18710
157 + 18553 = 18710
193 + 18517 = 18710
229 + 18481 = 18710
271 + 18439 = 18710

Showing the first eight; more decompositions exist.
