Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618884, here are decompositions:

5 + 8618879 = 8618884
17 + 8618867 = 8618884
23 + 8618861 = 8618884
101 + 8618783 = 8618884
137 + 8618747 = 8618884
293 + 8618591 = 8618884
317 + 8618567 = 8618884
383 + 8618501 = 8618884

Showing the first eight; more decompositions exist.
