Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8662418, here are decompositions:

7 + 8662411 = 8662418
139 + 8662279 = 8662418
199 + 8662219 = 8662418
229 + 8662189 = 8662418
241 + 8662177 = 8662418
397 + 8662021 = 8662418
409 + 8662009 = 8662418
421 + 8661997 = 8662418

Showing the first eight; more decompositions exist.
