Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739488, here are decompositions:

7 + 8739481 = 8739488
97 + 8739391 = 8739488
139 + 8739349 = 8739488
151 + 8739337 = 8739488
157 + 8739331 = 8739488
409 + 8739079 = 8739488
487 + 8739001 = 8739488
607 + 8738881 = 8739488

Showing the first eight; more decompositions exist.
