Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588066, here are decompositions:

5 + 31588061 = 31588066
47 + 31588019 = 31588066
173 + 31587893 = 31588066
317 + 31587749 = 31588066
359 + 31587707 = 31588066
443 + 31587623 = 31588066
449 + 31587617 = 31588066
479 + 31587587 = 31588066

Showing the first eight; more decompositions exist.
