Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588074, here are decompositions:

13 + 31588061 = 31588074
71 + 31588003 = 31588074
113 + 31587961 = 31588074
131 + 31587943 = 31588074
151 + 31587923 = 31588074
163 + 31587911 = 31588074
181 + 31587893 = 31588074
197 + 31587877 = 31588074

Showing the first eight; more decompositions exist.
