Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31587334, here are decompositions:

17 + 31587317 = 31587334
47 + 31587287 = 31587334
71 + 31587263 = 31587334
83 + 31587251 = 31587334
113 + 31587221 = 31587334
137 + 31587197 = 31587334
167 + 31587167 = 31587334
173 + 31587161 = 31587334

Showing the first eight; more decompositions exist.
