Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649038, here are decompositions:

37 + 8649001 = 8649038
109 + 8648929 = 8649038
157 + 8648881 = 8649038
199 + 8648839 = 8649038
241 + 8648797 = 8649038
337 + 8648701 = 8649038
487 + 8648551 = 8649038
691 + 8648347 = 8649038

Showing the first eight; more decompositions exist.
