Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8619464, here are decompositions:

3 + 8619461 = 8619464
31 + 8619433 = 8619464
37 + 8619427 = 8619464
43 + 8619421 = 8619464
67 + 8619397 = 8619464
223 + 8619241 = 8619464
241 + 8619223 = 8619464
307 + 8619157 = 8619464

Showing the first eight; more decompositions exist.
