Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8591738, here are decompositions:

139 + 8591599 = 8591738
151 + 8591587 = 8591738
271 + 8591467 = 8591738
307 + 8591431 = 8591738
349 + 8591389 = 8591738
439 + 8591299 = 8591738
487 + 8591251 = 8591738
607 + 8591131 = 8591738

Showing the first eight; more decompositions exist.
