Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618126, here are decompositions:

7 + 8618119 = 8618126
19 + 8618107 = 8618126
37 + 8618089 = 8618126
43 + 8618083 = 8618126
67 + 8618059 = 8618126
79 + 8618047 = 8618126
193 + 8617933 = 8618126
199 + 8617927 = 8618126

Showing the first eight; more decompositions exist.
