Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8745822, here are decompositions:

5 + 8745817 = 8745822
23 + 8745799 = 8745822
73 + 8745749 = 8745822
79 + 8745743 = 8745822
139 + 8745683 = 8745822
251 + 8745571 = 8745822
269 + 8745553 = 8745822
271 + 8745551 = 8745822

Showing the first eight; more decompositions exist.
