Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618244, here are decompositions:

7 + 8618237 = 8618244
23 + 8618221 = 8618244
31 + 8618213 = 8618244
71 + 8618173 = 8618244
97 + 8618147 = 8618244
113 + 8618131 = 8618244
137 + 8618107 = 8618244
157 + 8618087 = 8618244

Showing the first eight; more decompositions exist.
