Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621430, here are decompositions:

17 + 8621413 = 8621430
19 + 8621411 = 8621430
53 + 8621377 = 8621430
131 + 8621299 = 8621430
149 + 8621281 = 8621430
193 + 8621237 = 8621430
229 + 8621201 = 8621430
241 + 8621189 = 8621430

Showing the first eight; more decompositions exist.
