Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8653684, here are decompositions:

5 + 8653679 = 8653684
71 + 8653613 = 8653684
131 + 8653553 = 8653684
167 + 8653517 = 8653684
197 + 8653487 = 8653684
227 + 8653457 = 8653684
311 + 8653373 = 8653684
401 + 8653283 = 8653684

Showing the first eight; more decompositions exist.
