Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452036, here are decompositions:

17 + 31452019 = 31452036
23 + 31452013 = 31452036
29 + 31452007 = 31452036
37 + 31451999 = 31452036
43 + 31451993 = 31452036
67 + 31451969 = 31452036
107 + 31451929 = 31452036
127 + 31451909 = 31452036

Showing the first eight; more decompositions exist.
