Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8759420, here are decompositions:

13 + 8759407 = 8759420
67 + 8759353 = 8759420
73 + 8759347 = 8759420
199 + 8759221 = 8759420
283 + 8759137 = 8759420
331 + 8759089 = 8759420
433 + 8758987 = 8759420
487 + 8758933 = 8759420

Showing the first eight; more decompositions exist.
