Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719040, here are decompositions:

3 + 8719037 = 8719040
19 + 8719021 = 8719040
37 + 8719003 = 8719040
67 + 8718973 = 8719040
163 + 8718877 = 8719040
181 + 8718859 = 8719040
229 + 8718811 = 8719040
241 + 8718799 = 8719040

Showing the first eight; more decompositions exist.
