Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582476, here are decompositions:

5 + 31582471 = 31582476
59 + 31582417 = 31582476
67 + 31582409 = 31582476
73 + 31582403 = 31582476
139 + 31582337 = 31582476
157 + 31582319 = 31582476
227 + 31582249 = 31582476
269 + 31582207 = 31582476

Showing the first eight; more decompositions exist.
