Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19040, here are decompositions:

3 + 19037 = 19040
31 + 19009 = 19040
61 + 18979 = 19040
67 + 18973 = 19040
127 + 18913 = 19040
181 + 18859 = 19040
283 + 18757 = 19040
349 + 18691 = 19040

Showing the first eight; more decompositions exist.
