Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446700, here are decompositions:

11 + 31446689 = 31446700
59 + 31446641 = 31446700
107 + 31446593 = 31446700
137 + 31446563 = 31446700
167 + 31446533 = 31446700
239 + 31446461 = 31446700
359 + 31446341 = 31446700
443 + 31446257 = 31446700

Showing the first eight; more decompositions exist.
