Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618522, here are decompositions:

43 + 8618479 = 8618522
79 + 8618443 = 8618522
109 + 8618413 = 8618522
193 + 8618329 = 8618522
229 + 8618293 = 8618522
271 + 8618251 = 8618522
349 + 8618173 = 8618522
373 + 8618149 = 8618522

Showing the first eight; more decompositions exist.
