Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544268, here are decompositions:

47 + 31544221 = 31544268
61 + 31544207 = 31544268
79 + 31544189 = 31544268
89 + 31544179 = 31544268
97 + 31544171 = 31544268
101 + 31544167 = 31544268
137 + 31544131 = 31544268
179 + 31544089 = 31544268

Showing the first eight; more decompositions exist.
