Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739872, here are decompositions:

3 + 8739869 = 8739872
61 + 8739811 = 8739872
103 + 8739769 = 8739872
151 + 8739721 = 8739872
199 + 8739673 = 8739872
373 + 8739499 = 8739872
409 + 8739463 = 8739872
439 + 8739433 = 8739872

Showing the first eight; more decompositions exist.
