Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446600, here are decompositions:

7 + 31446593 = 31446600
37 + 31446563 = 31446600
43 + 31446557 = 31446600
47 + 31446553 = 31446600
67 + 31446533 = 31446600
109 + 31446491 = 31446600
139 + 31446461 = 31446600
173 + 31446427 = 31446600

Showing the first eight; more decompositions exist.
