Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621382, here are decompositions:

5 + 8621377 = 8621382
43 + 8621339 = 8621382
73 + 8621309 = 8621382
83 + 8621299 = 8621382
101 + 8621281 = 8621382
139 + 8621243 = 8621382
173 + 8621209 = 8621382
181 + 8621201 = 8621382

Showing the first eight; more decompositions exist.
