Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8761378, here are decompositions:

89 + 8761289 = 8761378
239 + 8761139 = 8761378
359 + 8761019 = 8761378
401 + 8760977 = 8761378
419 + 8760959 = 8761378
467 + 8760911 = 8761378
569 + 8760809 = 8761378
599 + 8760779 = 8761378

Showing the first eight; more decompositions exist.
