Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739128, here are decompositions:

31 + 8739097 = 8739128
127 + 8739001 = 8739128
199 + 8738929 = 8739128
421 + 8738707 = 8739128
457 + 8738671 = 8739128
487 + 8738641 = 8739128
547 + 8738581 = 8739128
691 + 8738437 = 8739128

Showing the first eight; more decompositions exist.
