Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988874, here are decompositions:

13 + 988861 = 988874
37 + 988837 = 988874
163 + 988711 = 988874
181 + 988693 = 988874
193 + 988681 = 988874
223 + 988651 = 988874
283 + 988591 = 988874
373 + 988501 = 988874

Showing the first eight; more decompositions exist.
