Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621374, here are decompositions:

131 + 8621243 = 8621374
137 + 8621237 = 8621374
173 + 8621201 = 8621374
191 + 8621183 = 8621374
227 + 8621147 = 8621374
401 + 8620973 = 8621374
431 + 8620943 = 8621374
617 + 8620757 = 8621374

Showing the first eight; more decompositions exist.
