Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8591732, here are decompositions:

43 + 8591689 = 8591732
109 + 8591623 = 8591732
139 + 8591593 = 8591732
199 + 8591533 = 8591732
283 + 8591449 = 8591732
313 + 8591419 = 8591732
421 + 8591311 = 8591732
433 + 8591299 = 8591732

Showing the first eight; more decompositions exist.
