Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719424, here are decompositions:

3 + 8719421 = 8719424
97 + 8719327 = 8719424
151 + 8719273 = 8719424
163 + 8719261 = 8719424
211 + 8719213 = 8719424
283 + 8719141 = 8719424
367 + 8719057 = 8719424
421 + 8719003 = 8719424

Showing the first eight; more decompositions exist.
