Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641738, here are decompositions:

5 + 8641733 = 8641738
29 + 8641709 = 8641738
41 + 8641697 = 8641738
107 + 8641631 = 8641738
167 + 8641571 = 8641738
191 + 8641547 = 8641738
197 + 8641541 = 8641738
269 + 8641469 = 8641738

Showing the first eight; more decompositions exist.
