Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641706, here are decompositions:

37 + 8641669 = 8641706
103 + 8641603 = 8641706
163 + 8641543 = 8641706
193 + 8641513 = 8641706
277 + 8641429 = 8641706
379 + 8641327 = 8641706
397 + 8641309 = 8641706
433 + 8641273 = 8641706

Showing the first eight; more decompositions exist.
