Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722074, here are decompositions:

41 + 8722033 = 8722074
47 + 8722027 = 8722074
73 + 8722001 = 8722074
157 + 8721917 = 8722074
167 + 8721907 = 8722074
191 + 8721883 = 8722074
197 + 8721877 = 8722074
223 + 8721851 = 8722074

Showing the first eight; more decompositions exist.
