Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468600, here are decompositions:

3 + 31468597 = 31468600
11 + 31468589 = 31468600
29 + 31468571 = 31468600
41 + 31468559 = 31468600
47 + 31468553 = 31468600
71 + 31468529 = 31468600
83 + 31468517 = 31468600
89 + 31468511 = 31468600

Showing the first eight; more decompositions exist.
