Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544020, here are decompositions:

23 + 31543997 = 31544020
29 + 31543991 = 31544020
41 + 31543979 = 31544020
59 + 31543961 = 31544020
107 + 31543913 = 31544020
113 + 31543907 = 31544020
149 + 31543871 = 31544020
173 + 31543847 = 31544020

Showing the first eight; more decompositions exist.
