Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739920, here are decompositions:

3 + 8739917 = 8739920
19 + 8739901 = 8739920
37 + 8739883 = 8739920
43 + 8739877 = 8739920
97 + 8739823 = 8739920
109 + 8739811 = 8739920
151 + 8739769 = 8739920
181 + 8739739 = 8739920

Showing the first eight; more decompositions exist.
