Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649902, here are decompositions:

31 + 8649871 = 8649902
109 + 8649793 = 8649902
139 + 8649763 = 8649902
181 + 8649721 = 8649902
199 + 8649703 = 8649902
211 + 8649691 = 8649902
241 + 8649661 = 8649902
433 + 8649469 = 8649902

Showing the first eight; more decompositions exist.
