Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644684, here are decompositions:

5 + 8644679 = 8644684
23 + 8644661 = 8644684
131 + 8644553 = 8644684
173 + 8644511 = 8644684
227 + 8644457 = 8644684
233 + 8644451 = 8644684
353 + 8644331 = 8644684
383 + 8644301 = 8644684

Showing the first eight; more decompositions exist.
