Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8721068, here are decompositions:

7 + 8721061 = 8721068
19 + 8721049 = 8721068
127 + 8720941 = 8721068
157 + 8720911 = 8721068
229 + 8720839 = 8721068
271 + 8720797 = 8721068
379 + 8720689 = 8721068
397 + 8720671 = 8721068

Showing the first eight; more decompositions exist.
