Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618408, here are decompositions:

31 + 8618377 = 8618408
79 + 8618329 = 8618408
151 + 8618257 = 8618408
157 + 8618251 = 8618408
277 + 8618131 = 8618408
349 + 8618059 = 8618408
367 + 8618041 = 8618408
571 + 8617837 = 8618408

Showing the first eight; more decompositions exist.
