Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8591772, here are decompositions:

61 + 8591711 = 8591772
83 + 8591689 = 8591772
89 + 8591683 = 8591772
109 + 8591663 = 8591772
139 + 8591633 = 8591772
149 + 8591623 = 8591772
173 + 8591599 = 8591772
179 + 8591593 = 8591772

Showing the first eight; more decompositions exist.
