Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988564, here are decompositions:

23 + 988541 = 988564
53 + 988511 = 988564
197 + 988367 = 988564
251 + 988313 = 988564
293 + 988271 = 988564
347 + 988217 = 988564
503 + 988061 = 988564
557 + 988007 = 988564

Showing the first eight; more decompositions exist.
