Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31447336, here are decompositions:

3 + 31447333 = 31447336
83 + 31447253 = 31447336
233 + 31447103 = 31447336
257 + 31447079 = 31447336
293 + 31447043 = 31447336
317 + 31447019 = 31447336
353 + 31446983 = 31447336
383 + 31446953 = 31447336

Showing the first eight; more decompositions exist.
