Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8658444, here are decompositions:

13 + 8658431 = 8658444
31 + 8658413 = 8658444
61 + 8658383 = 8658444
73 + 8658371 = 8658444
131 + 8658313 = 8658444
167 + 8658277 = 8658444
211 + 8658233 = 8658444
227 + 8658217 = 8658444

Showing the first eight; more decompositions exist.
