Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8708772, here are decompositions:

31 + 8708741 = 8708772
41 + 8708731 = 8708772
71 + 8708701 = 8708772
109 + 8708663 = 8708772
151 + 8708621 = 8708772
181 + 8708591 = 8708772
251 + 8708521 = 8708772
263 + 8708509 = 8708772

Showing the first eight; more decompositions exist.
