Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687248, here are decompositions:

41 + 8687207 = 8687248
107 + 8687141 = 8687248
131 + 8687117 = 8687248
179 + 8687069 = 8687248
347 + 8686901 = 8687248
359 + 8686889 = 8687248
419 + 8686829 = 8687248
569 + 8686679 = 8687248

Showing the first eight; more decompositions exist.
