Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582446, here are decompositions:

29 + 31582417 = 31582446
37 + 31582409 = 31582446
43 + 31582403 = 31582446
47 + 31582399 = 31582446
109 + 31582337 = 31582446
113 + 31582333 = 31582446
127 + 31582319 = 31582446
179 + 31582267 = 31582446

Showing the first eight; more decompositions exist.
