Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719524, here are decompositions:

5 + 8719519 = 8719524
41 + 8719483 = 8719524
83 + 8719441 = 8719524
103 + 8719421 = 8719524
157 + 8719367 = 8719524
197 + 8719327 = 8719524
223 + 8719301 = 8719524
251 + 8719273 = 8719524

Showing the first eight; more decompositions exist.
