Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582350, here are decompositions:

13 + 31582337 = 31582350
17 + 31582333 = 31582350
29 + 31582321 = 31582350
31 + 31582319 = 31582350
83 + 31582267 = 31582350
101 + 31582249 = 31582350
109 + 31582241 = 31582350
157 + 31582193 = 31582350

Showing the first eight; more decompositions exist.
