Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582374, here are decompositions:

37 + 31582337 = 31582374
41 + 31582333 = 31582374
53 + 31582321 = 31582374
107 + 31582267 = 31582374
157 + 31582217 = 31582374
167 + 31582207 = 31582374
181 + 31582193 = 31582374
191 + 31582183 = 31582374

Showing the first eight; more decompositions exist.
