Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474336, here are decompositions:

17 + 31474319 = 31474336
29 + 31474307 = 31474336
83 + 31474253 = 31474336
263 + 31474073 = 31474336
293 + 31474043 = 31474336
359 + 31473977 = 31474336
419 + 31473917 = 31474336
449 + 31473887 = 31474336

Showing the first eight; more decompositions exist.
