Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618822, here are decompositions:

13 + 8618809 = 8618822
73 + 8618749 = 8618822
139 + 8618683 = 8618822
229 + 8618593 = 8618822
241 + 8618581 = 8618822
379 + 8618443 = 8618822
409 + 8618413 = 8618822
571 + 8618251 = 8618822

Showing the first eight; more decompositions exist.
