Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588084, here are decompositions:

23 + 31588061 = 31588084
173 + 31587911 = 31588084
191 + 31587893 = 31588084
317 + 31587767 = 31588084
347 + 31587737 = 31588084
383 + 31587701 = 31588084
461 + 31587623 = 31588084
467 + 31587617 = 31588084

Showing the first eight; more decompositions exist.
