Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550548, here are decompositions:

5 + 31550543 = 31550548
11 + 31550537 = 31550548
17 + 31550531 = 31550548
89 + 31550459 = 31550548
101 + 31550447 = 31550548
191 + 31550357 = 31550548
347 + 31550201 = 31550548
521 + 31550027 = 31550548

Showing the first eight; more decompositions exist.
