Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31587414, here are decompositions:

7 + 31587407 = 31587414
17 + 31587397 = 31587414
73 + 31587341 = 31587414
97 + 31587317 = 31587414
127 + 31587287 = 31587414
151 + 31587263 = 31587414
163 + 31587251 = 31587414
191 + 31587223 = 31587414

Showing the first eight; more decompositions exist.
