Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739884, here are decompositions:

7 + 8739877 = 8739884
61 + 8739823 = 8739884
73 + 8739811 = 8739884
163 + 8739721 = 8739884
211 + 8739673 = 8739884
277 + 8739607 = 8739884
421 + 8739463 = 8739884
487 + 8739397 = 8739884

Showing the first eight; more decompositions exist.
