Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446760, here are decompositions:

3 + 31446757 = 31446760
11 + 31446749 = 31446760
17 + 31446743 = 31446760
71 + 31446689 = 31446760
167 + 31446593 = 31446760
197 + 31446563 = 31446760
227 + 31446533 = 31446760
269 + 31446491 = 31446760

Showing the first eight; more decompositions exist.
