Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738392, here are decompositions:

29 + 8738363 = 8738392
41 + 8738351 = 8738392
53 + 8738339 = 8738392
59 + 8738333 = 8738392
191 + 8738201 = 8738392
263 + 8738129 = 8738392
269 + 8738123 = 8738392
359 + 8738033 = 8738392

Showing the first eight; more decompositions exist.
