Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582314, here are decompositions:

47 + 31582267 = 31582314
73 + 31582241 = 31582314
97 + 31582217 = 31582314
107 + 31582207 = 31582314
131 + 31582183 = 31582314
151 + 31582163 = 31582314
193 + 31582121 = 31582314
271 + 31582043 = 31582314

Showing the first eight; more decompositions exist.
