Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640370, here are decompositions:

41 + 8640329 = 8640370
83 + 8640287 = 8640370
107 + 8640263 = 8640370
149 + 8640221 = 8640370
173 + 8640197 = 8640370
311 + 8640059 = 8640370
353 + 8640017 = 8640370
383 + 8639987 = 8640370

Showing the first eight; more decompositions exist.
