Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472344, here are decompositions:

5 + 31472339 = 31472344
53 + 31472291 = 31472344
83 + 31472261 = 31472344
191 + 31472153 = 31472344
353 + 31471991 = 31472344
443 + 31471901 = 31472344
461 + 31471883 = 31472344
521 + 31471823 = 31472344

Showing the first eight; more decompositions exist.
