Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472392, here are decompositions:

41 + 31472351 = 31472392
53 + 31472339 = 31472392
101 + 31472291 = 31472392
131 + 31472261 = 31472392
191 + 31472201 = 31472392
233 + 31472159 = 31472392
239 + 31472153 = 31472392
269 + 31472123 = 31472392

Showing the first eight; more decompositions exist.
