Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724418, here are decompositions:

41 + 8724377 = 8724418
47 + 8724371 = 8724418
71 + 8724347 = 8724418
89 + 8724329 = 8724418
107 + 8724311 = 8724418
149 + 8724269 = 8724418
257 + 8724161 = 8724418
317 + 8724101 = 8724418

Showing the first eight; more decompositions exist.
