Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8591658, here are decompositions:

41 + 8591617 = 8591658
59 + 8591599 = 8591658
71 + 8591587 = 8591658
109 + 8591549 = 8591658
139 + 8591519 = 8591658
151 + 8591507 = 8591658
157 + 8591501 = 8591658
191 + 8591467 = 8591658

Showing the first eight; more decompositions exist.
