Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573554, here are decompositions:

31 + 31573523 = 31573554
41 + 31573513 = 31573554
53 + 31573501 = 31573554
127 + 31573427 = 31573554
163 + 31573391 = 31573554
191 + 31573363 = 31573554
193 + 31573361 = 31573554
197 + 31573357 = 31573554

Showing the first eight; more decompositions exist.
