Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618882, here are decompositions:

3 + 8618879 = 8618882
31 + 8618851 = 8618882
73 + 8618809 = 8618882
193 + 8618689 = 8618882
199 + 8618683 = 8618882
439 + 8618443 = 8618882
631 + 8618251 = 8618882
661 + 8618221 = 8618882

Showing the first eight; more decompositions exist.
