Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672420, here are decompositions:

13 + 8672407 = 8672420
67 + 8672353 = 8672420
73 + 8672347 = 8672420
157 + 8672263 = 8672420
181 + 8672239 = 8672420
373 + 8672047 = 8672420
433 + 8671987 = 8672420
439 + 8671981 = 8672420

Showing the first eight; more decompositions exist.
