Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645902, here are decompositions:

3 + 8645899 = 8645902
53 + 8645849 = 8645902
113 + 8645789 = 8645902
173 + 8645729 = 8645902
233 + 8645669 = 8645902
269 + 8645633 = 8645902
359 + 8645543 = 8645902
521 + 8645381 = 8645902

Showing the first eight; more decompositions exist.
