Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618248, here are decompositions:

5 + 8618243 = 8618248
11 + 8618237 = 8618248
101 + 8618147 = 8618248
227 + 8618021 = 8618248
257 + 8617991 = 8618248
449 + 8617799 = 8618248
461 + 8617787 = 8618248
479 + 8617769 = 8618248

Showing the first eight; more decompositions exist.
