Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8721954, here are decompositions:

13 + 8721941 = 8721954
37 + 8721917 = 8721954
41 + 8721913 = 8721954
47 + 8721907 = 8721954
71 + 8721883 = 8721954
103 + 8721851 = 8721954
181 + 8721773 = 8721954
191 + 8721763 = 8721954

Showing the first eight; more decompositions exist.
