Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8709518, here are decompositions:

157 + 8709361 = 8709518
229 + 8709289 = 8709518
331 + 8709187 = 8709518
379 + 8709139 = 8709518
397 + 8709121 = 8709518
439 + 8709079 = 8709518
547 + 8708971 = 8709518
607 + 8708911 = 8709518

Showing the first eight; more decompositions exist.
