Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472268, here are decompositions:

7 + 31472261 = 31472268
29 + 31472239 = 31472268
59 + 31472209 = 31472268
67 + 31472201 = 31472268
89 + 31472179 = 31472268
101 + 31472167 = 31472268
109 + 31472159 = 31472268
137 + 31472131 = 31472268

Showing the first eight; more decompositions exist.
