Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8591884, here are decompositions:

53 + 8591831 = 8591884
71 + 8591813 = 8591884
113 + 8591771 = 8591884
137 + 8591747 = 8591884
167 + 8591717 = 8591884
173 + 8591711 = 8591884
251 + 8591633 = 8591884
281 + 8591603 = 8591884

Showing the first eight; more decompositions exist.
