Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739808, here are decompositions:

5 + 8739803 = 8739808
41 + 8739767 = 8739808
59 + 8739749 = 8739808
137 + 8739671 = 8739808
191 + 8739617 = 8739808
317 + 8739491 = 8739808
419 + 8739389 = 8739808
449 + 8739359 = 8739808

Showing the first eight; more decompositions exist.
