Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988578, here are decompositions:

7 + 988571 = 988578
29 + 988549 = 988578
37 + 988541 = 988578
67 + 988511 = 988578
89 + 988489 = 988578
139 + 988439 = 988578
211 + 988367 = 988578
257 + 988321 = 988578

Showing the first eight; more decompositions exist.
