Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8758838, here are decompositions:

19 + 8758819 = 8758838
37 + 8758801 = 8758838
61 + 8758777 = 8758838
241 + 8758597 = 8758838
331 + 8758507 = 8758838
337 + 8758501 = 8758838
379 + 8758459 = 8758838
409 + 8758429 = 8758838

Showing the first eight; more decompositions exist.
