Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8709780, here are decompositions:

29 + 8709751 = 8709780
43 + 8709737 = 8709780
59 + 8709721 = 8709780
61 + 8709719 = 8709780
67 + 8709713 = 8709780
83 + 8709697 = 8709780
103 + 8709677 = 8709780
127 + 8709653 = 8709780

Showing the first eight; more decompositions exist.
