Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8755438, here are decompositions:

59 + 8755379 = 8755438
89 + 8755349 = 8755438
101 + 8755337 = 8755438
191 + 8755247 = 8755438
317 + 8755121 = 8755438
359 + 8755079 = 8755438
389 + 8755049 = 8755438
467 + 8754971 = 8755438

Showing the first eight; more decompositions exist.
