Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474306, here are decompositions:

5 + 31474301 = 31474306
53 + 31474253 = 31474306
89 + 31474217 = 31474306
233 + 31474073 = 31474306
263 + 31474043 = 31474306
389 + 31473917 = 31474306
419 + 31473887 = 31474306
443 + 31473863 = 31474306

Showing the first eight; more decompositions exist.
