Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655146, here are decompositions:

43 + 8655103 = 8655146
109 + 8655037 = 8655146
139 + 8655007 = 8655146
229 + 8654917 = 8655146
307 + 8654839 = 8655146
337 + 8654809 = 8655146
373 + 8654773 = 8655146
397 + 8654749 = 8655146

Showing the first eight; more decompositions exist.
