Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621232, here are decompositions:

19 + 8621213 = 8621232
23 + 8621209 = 8621232
31 + 8621201 = 8621232
43 + 8621189 = 8621232
79 + 8621153 = 8621232
89 + 8621143 = 8621232
131 + 8621101 = 8621232
149 + 8621083 = 8621232

Showing the first eight; more decompositions exist.
