Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8702800, here are decompositions:

23 + 8702777 = 8702800
47 + 8702753 = 8702800
53 + 8702747 = 8702800
101 + 8702699 = 8702800
107 + 8702693 = 8702800
137 + 8702663 = 8702800
257 + 8702543 = 8702800
311 + 8702489 = 8702800

Showing the first eight; more decompositions exist.
