Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544184, here are decompositions:

5 + 31544179 = 31544184
13 + 31544171 = 31544184
17 + 31544167 = 31544184
31 + 31544153 = 31544184
53 + 31544131 = 31544184
107 + 31544077 = 31544184
127 + 31544057 = 31544184
131 + 31544053 = 31544184

Showing the first eight; more decompositions exist.
