Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621230, here are decompositions:

17 + 8621213 = 8621230
29 + 8621201 = 8621230
41 + 8621189 = 8621230
47 + 8621183 = 8621230
83 + 8621147 = 8621230
179 + 8621051 = 8621230
257 + 8620973 = 8621230
281 + 8620949 = 8621230

Showing the first eight; more decompositions exist.
