Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641904, here are decompositions:

13 + 8641891 = 8641904
31 + 8641873 = 8641904
97 + 8641807 = 8641904
157 + 8641747 = 8641904
163 + 8641741 = 8641904
283 + 8641621 = 8641904
433 + 8641471 = 8641904
577 + 8641327 = 8641904

Showing the first eight; more decompositions exist.
