Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621274, here are decompositions:

31 + 8621243 = 8621274
37 + 8621237 = 8621274
61 + 8621213 = 8621274
73 + 8621201 = 8621274
127 + 8621147 = 8621274
131 + 8621143 = 8621274
173 + 8621101 = 8621274
191 + 8621083 = 8621274

Showing the first eight; more decompositions exist.
