Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618208, here are decompositions:

59 + 8618149 = 8618208
61 + 8618147 = 8618208
89 + 8618119 = 8618208
101 + 8618107 = 8618208
149 + 8618059 = 8618208
167 + 8618041 = 8618208
281 + 8617927 = 8618208
331 + 8617877 = 8618208

Showing the first eight; more decompositions exist.
