Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544010, here are decompositions:

13 + 31543997 = 31544010
19 + 31543991 = 31544010
23 + 31543987 = 31544010
31 + 31543979 = 31544010
83 + 31543927 = 31544010
97 + 31543913 = 31544010
103 + 31543907 = 31544010
107 + 31543903 = 31544010

Showing the first eight; more decompositions exist.
