Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31580334, here are decompositions:

7 + 31580327 = 31580334
11 + 31580323 = 31580334
13 + 31580321 = 31580334
17 + 31580317 = 31580334
41 + 31580293 = 31580334
61 + 31580273 = 31580334
67 + 31580267 = 31580334
101 + 31580233 = 31580334

Showing the first eight; more decompositions exist.
