Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8721092, here are decompositions:

13 + 8721079 = 8721092
31 + 8721061 = 8721092
43 + 8721049 = 8721092
139 + 8720953 = 8721092
151 + 8720941 = 8721092
181 + 8720911 = 8721092
283 + 8720809 = 8721092
379 + 8720713 = 8721092

Showing the first eight; more decompositions exist.
