Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606658, here are decompositions:

7 + 31606651 = 31606658
79 + 31606579 = 31606658
229 + 31606429 = 31606658
271 + 31606387 = 31606658
277 + 31606381 = 31606658
379 + 31606279 = 31606658
397 + 31606261 = 31606658
571 + 31606087 = 31606658

Showing the first eight; more decompositions exist.
