Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8591624, here are decompositions:

7 + 8591617 = 8591624
31 + 8591593 = 8591624
37 + 8591587 = 8591624
61 + 8591563 = 8591624
157 + 8591467 = 8591624
193 + 8591431 = 8591624
313 + 8591311 = 8591624
331 + 8591293 = 8591624

Showing the first eight; more decompositions exist.
