Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655382, here are decompositions:

11 + 8655371 = 8655382
233 + 8655149 = 8655382
311 + 8655071 = 8655382
353 + 8655029 = 8655382
401 + 8654981 = 8655382
509 + 8654873 = 8655382
653 + 8654729 = 8655382
719 + 8654663 = 8655382

Showing the first eight; more decompositions exist.
