Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452066, here are decompositions:

5 + 31452061 = 31452066
47 + 31452019 = 31452066
53 + 31452013 = 31452066
59 + 31452007 = 31452066
67 + 31451999 = 31452066
73 + 31451993 = 31452066
97 + 31451969 = 31452066
137 + 31451929 = 31452066

Showing the first eight; more decompositions exist.
