Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642902, here are decompositions:

5 + 8642897 = 8642902
41 + 8642861 = 8642902
53 + 8642849 = 8642902
83 + 8642819 = 8642902
179 + 8642723 = 8642902
251 + 8642651 = 8642902
269 + 8642633 = 8642902
311 + 8642591 = 8642902

Showing the first eight; more decompositions exist.
