Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8591842, here are decompositions:

11 + 8591831 = 8591842
29 + 8591813 = 8591842
71 + 8591771 = 8591842
131 + 8591711 = 8591842
179 + 8591663 = 8591842
239 + 8591603 = 8591842
269 + 8591573 = 8591842
293 + 8591549 = 8591842

Showing the first eight; more decompositions exist.
