Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8651998, here are decompositions:

59 + 8651939 = 8651998
107 + 8651891 = 8651998
227 + 8651771 = 8651998
281 + 8651717 = 8651998
359 + 8651639 = 8651998
389 + 8651609 = 8651998
419 + 8651579 = 8651998
449 + 8651549 = 8651998

Showing the first eight; more decompositions exist.
