Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644904, here are decompositions:

31 + 8644873 = 8644904
43 + 8644861 = 8644904
61 + 8644843 = 8644904
181 + 8644723 = 8644904
271 + 8644633 = 8644904
397 + 8644507 = 8644904
577 + 8644327 = 8644904
643 + 8644261 = 8644904

Showing the first eight; more decompositions exist.
