Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8709020, here are decompositions:

13 + 8709007 = 8709020
109 + 8708911 = 8709020
127 + 8708893 = 8709020
409 + 8708611 = 8709020
499 + 8708521 = 8709020
571 + 8708449 = 8709020
751 + 8708269 = 8709020
823 + 8708197 = 8709020

Showing the first eight; more decompositions exist.
