Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588010, here are decompositions:

7 + 31588003 = 31588010
31 + 31587979 = 31588010
61 + 31587949 = 31588010
67 + 31587943 = 31588010
151 + 31587859 = 31588010
193 + 31587817 = 31588010
211 + 31587799 = 31588010
229 + 31587781 = 31588010

Showing the first eight; more decompositions exist.
