Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31587364, here are decompositions:

23 + 31587341 = 31587364
47 + 31587317 = 31587364
101 + 31587263 = 31587364
113 + 31587251 = 31587364
167 + 31587197 = 31587364
197 + 31587167 = 31587364
227 + 31587137 = 31587364
257 + 31587107 = 31587364

Showing the first eight; more decompositions exist.
