Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544106, here are decompositions:

7 + 31544099 = 31544106
17 + 31544089 = 31544106
29 + 31544077 = 31544106
53 + 31544053 = 31544106
67 + 31544039 = 31544106
73 + 31544033 = 31544106
109 + 31543997 = 31544106
127 + 31543979 = 31544106

Showing the first eight; more decompositions exist.
