Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648492, here are decompositions:

79 + 8648413 = 8648492
103 + 8648389 = 8648492
241 + 8648251 = 8648492
271 + 8648221 = 8648492
313 + 8648179 = 8648492
379 + 8648113 = 8648492
409 + 8648083 = 8648492
499 + 8647993 = 8648492

Showing the first eight; more decompositions exist.
