Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573526, here are decompositions:

3 + 31573523 = 31573526
13 + 31573513 = 31573526
163 + 31573363 = 31573526
337 + 31573189 = 31573526
373 + 31573153 = 31573526
433 + 31573093 = 31573526
499 + 31573027 = 31573526
547 + 31572979 = 31573526

Showing the first eight; more decompositions exist.
