Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618402, here are decompositions:

73 + 8618329 = 8618402
109 + 8618293 = 8618402
151 + 8618251 = 8618402
181 + 8618221 = 8618402
229 + 8618173 = 8618402
271 + 8618131 = 8618402
283 + 8618119 = 8618402
313 + 8618089 = 8618402

Showing the first eight; more decompositions exist.
