Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989144, here are decompositions:

73 + 989071 = 989144
181 + 988963 = 989144
193 + 988951 = 989144
283 + 988861 = 989144
307 + 988837 = 989144
433 + 988711 = 989144
463 + 988681 = 989144
643 + 988501 = 989144

Showing the first eight; more decompositions exist.
