Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738858, here are decompositions:

19 + 8738839 = 8738858
151 + 8738707 = 8738858
199 + 8738659 = 8738858
277 + 8738581 = 8738858
367 + 8738491 = 8738858
409 + 8738449 = 8738858
421 + 8738437 = 8738858
577 + 8738281 = 8738858

Showing the first eight; more decompositions exist.
