Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618258, here are decompositions:

7 + 8618251 = 8618258
37 + 8618221 = 8618258
109 + 8618149 = 8618258
127 + 8618131 = 8618258
139 + 8618119 = 8618258
151 + 8618107 = 8618258
199 + 8618059 = 8618258
211 + 8618047 = 8618258

Showing the first eight; more decompositions exist.
