Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8591948, here are decompositions:

7 + 8591941 = 8591948
61 + 8591887 = 8591948
139 + 8591809 = 8591948
331 + 8591617 = 8591948
349 + 8591599 = 8591948
499 + 8591449 = 8591948
571 + 8591377 = 8591948
691 + 8591257 = 8591948

Showing the first eight; more decompositions exist.
