Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988544, here are decompositions:

3 + 988541 = 988544
43 + 988501 = 988544
61 + 988483 = 988544
127 + 988417 = 988544
223 + 988321 = 988544
307 + 988237 = 988544
313 + 988231 = 988544
331 + 988213 = 988544

Showing the first eight; more decompositions exist.
