Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548988, here are decompositions:

5 + 31548983 = 31548988
131 + 31548857 = 31548988
239 + 31548749 = 31548988
311 + 31548677 = 31548988
347 + 31548641 = 31548988
461 + 31548527 = 31548988
467 + 31548521 = 31548988
521 + 31548467 = 31548988

Showing the first eight; more decompositions exist.
