Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452242, here are decompositions:

43 + 31452199 = 31452242
61 + 31452181 = 31452242
163 + 31452079 = 31452242
181 + 31452061 = 31452242
223 + 31452019 = 31452242
229 + 31452013 = 31452242
313 + 31451929 = 31452242
373 + 31451869 = 31452242

Showing the first eight; more decompositions exist.
