Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618426, here are decompositions:

13 + 8618413 = 8618426
97 + 8618329 = 8618426
109 + 8618317 = 8618426
139 + 8618287 = 8618426
277 + 8618149 = 8618426
307 + 8618119 = 8618426
337 + 8618089 = 8618426
367 + 8618059 = 8618426

Showing the first eight; more decompositions exist.
