Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588068, here are decompositions:

7 + 31588061 = 31588068
89 + 31587979 = 31588068
107 + 31587961 = 31588068
157 + 31587911 = 31588068
191 + 31587877 = 31588068
251 + 31587817 = 31588068
269 + 31587799 = 31588068
331 + 31587737 = 31588068

Showing the first eight; more decompositions exist.
