Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8721134, here are decompositions:

13 + 8721121 = 8721134
73 + 8721061 = 8721134
157 + 8720977 = 8721134
181 + 8720953 = 8721134
193 + 8720941 = 8721134
223 + 8720911 = 8721134
337 + 8720797 = 8721134
421 + 8720713 = 8721134

Showing the first eight; more decompositions exist.
