Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618178, here are decompositions:

5 + 8618173 = 8618178
29 + 8618149 = 8618178
31 + 8618147 = 8618178
47 + 8618131 = 8618178
59 + 8618119 = 8618178
71 + 8618107 = 8618178
89 + 8618089 = 8618178
131 + 8618047 = 8618178

Showing the first eight; more decompositions exist.
