Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452050, here are decompositions:

31 + 31452019 = 31452050
37 + 31452013 = 31452050
43 + 31452007 = 31452050
181 + 31451869 = 31452050
193 + 31451857 = 31452050
211 + 31451839 = 31452050
337 + 31451713 = 31452050
433 + 31451617 = 31452050

Showing the first eight; more decompositions exist.
