Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545404, here are decompositions:

3 + 31545401 = 31545404
13 + 31545391 = 31545404
31 + 31545373 = 31545404
61 + 31545343 = 31545404
73 + 31545331 = 31545404
193 + 31545211 = 31545404
223 + 31545181 = 31545404
307 + 31545097 = 31545404

Showing the first eight; more decompositions exist.
