Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8624690, here are decompositions:

13 + 8624677 = 8624690
73 + 8624617 = 8624690
241 + 8624449 = 8624690
307 + 8624383 = 8624690
337 + 8624353 = 8624690
367 + 8624323 = 8624690
379 + 8624311 = 8624690
439 + 8624251 = 8624690

Showing the first eight; more decompositions exist.
