Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989240, here are decompositions:

67 + 989173 = 989240
181 + 989059 = 989240
211 + 989029 = 989240
229 + 989011 = 989240
277 + 988963 = 989240
331 + 988909 = 989240
379 + 988861 = 989240
457 + 988783 = 989240

Showing the first eight; more decompositions exist.
