Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8721054, here are decompositions:

5 + 8721049 = 8721054
11 + 8721043 = 8721054
101 + 8720953 = 8721054
107 + 8720947 = 8721054
113 + 8720941 = 8721054
163 + 8720891 = 8721054
257 + 8720797 = 8721054
271 + 8720783 = 8721054

Showing the first eight; more decompositions exist.
