Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618462, here are decompositions:

19 + 8618443 = 8618462
211 + 8618251 = 8618462
241 + 8618221 = 8618462
313 + 8618149 = 8618462
331 + 8618131 = 8618462
373 + 8618089 = 8618462
379 + 8618083 = 8618462
421 + 8618041 = 8618462

Showing the first eight; more decompositions exist.
