Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466800, here are decompositions:

41 + 31466759 = 31466800
47 + 31466753 = 31466800
107 + 31466693 = 31466800
173 + 31466627 = 31466800
251 + 31466549 = 31466800
419 + 31466381 = 31466800
509 + 31466291 = 31466800
593 + 31466207 = 31466800

Showing the first eight; more decompositions exist.
