Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643274, here are decompositions:

131 + 8643143 = 8643274
137 + 8643137 = 8643274
191 + 8643083 = 8643274
197 + 8643077 = 8643274
251 + 8643023 = 8643274
347 + 8642927 = 8643274
641 + 8642633 = 8643274
683 + 8642591 = 8643274

Showing the first eight; more decompositions exist.
