Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19240, here are decompositions:

3 + 19237 = 19240
29 + 19211 = 19240
59 + 19181 = 19240
83 + 19157 = 19240
101 + 19139 = 19240
167 + 19073 = 19240
227 + 19013 = 19240
239 + 19001 = 19240

Showing the first eight; more decompositions exist.
