Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988624, here are decompositions:

17 + 988607 = 988624
41 + 988583 = 988624
47 + 988577 = 988624
53 + 988571 = 988624
83 + 988541 = 988624
113 + 988511 = 988624
257 + 988367 = 988624
281 + 988343 = 988624

Showing the first eight; more decompositions exist.
