Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8591992, here are decompositions:

29 + 8591963 = 8591992
83 + 8591909 = 8591992
179 + 8591813 = 8591992
281 + 8591711 = 8591992
359 + 8591633 = 8591992
389 + 8591603 = 8591992
419 + 8591573 = 8591992
443 + 8591549 = 8591992

Showing the first eight; more decompositions exist.
