Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988444, here are decompositions:

5 + 988439 = 988444
101 + 988343 = 988444
131 + 988313 = 988444
173 + 988271 = 988444
227 + 988217 = 988444
383 + 988061 = 988444
461 + 987983 = 988444
503 + 987941 = 988444

Showing the first eight; more decompositions exist.
