Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8709908, here are decompositions:

37 + 8709871 = 8709908
127 + 8709781 = 8709908
157 + 8709751 = 8709908
211 + 8709697 = 8709908
439 + 8709469 = 8709908
547 + 8709361 = 8709908
607 + 8709301 = 8709908
619 + 8709289 = 8709908

Showing the first eight; more decompositions exist.
