Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466650, here are decompositions:

23 + 31466627 = 31466650
53 + 31466597 = 31466650
101 + 31466549 = 31466650
263 + 31466387 = 31466650
269 + 31466381 = 31466650
359 + 31466291 = 31466650
401 + 31466249 = 31466650
443 + 31466207 = 31466650

Showing the first eight; more decompositions exist.
