Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8619122, here are decompositions:

163 + 8618959 = 8619122
199 + 8618923 = 8619122
229 + 8618893 = 8619122
271 + 8618851 = 8619122
313 + 8618809 = 8619122
373 + 8618749 = 8619122
433 + 8618689 = 8619122
439 + 8618683 = 8619122

Showing the first eight; more decompositions exist.
