Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641802, here are decompositions:

19 + 8641783 = 8641802
61 + 8641741 = 8641802
151 + 8641651 = 8641802
181 + 8641621 = 8641802
199 + 8641603 = 8641802
283 + 8641519 = 8641802
331 + 8641471 = 8641802
349 + 8641453 = 8641802

Showing the first eight; more decompositions exist.
