Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8708780, here are decompositions:

79 + 8708701 = 8708780
163 + 8708617 = 8708780
271 + 8708509 = 8708780
331 + 8708449 = 8708780
607 + 8708173 = 8708780
709 + 8708071 = 8708780
811 + 8707969 = 8708780
877 + 8707903 = 8708780

Showing the first eight; more decompositions exist.
