Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588048, here are decompositions:

29 + 31588019 = 31588048
137 + 31587911 = 31588048
269 + 31587779 = 31588048
281 + 31587767 = 31588048
311 + 31587737 = 31588048
347 + 31587701 = 31588048
389 + 31587659 = 31588048
431 + 31587617 = 31588048

Showing the first eight; more decompositions exist.
