Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642074, here are decompositions:

11 + 8642063 = 8642074
17 + 8642057 = 8642074
41 + 8642033 = 8642074
47 + 8642027 = 8642074
71 + 8642003 = 8642074
83 + 8641991 = 8642074
191 + 8641883 = 8642074
257 + 8641817 = 8642074

Showing the first eight; more decompositions exist.
