Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474246, here are decompositions:

29 + 31474217 = 31474246
173 + 31474073 = 31474246
239 + 31474007 = 31474246
269 + 31473977 = 31474246
359 + 31473887 = 31474246
383 + 31473863 = 31474246
467 + 31473779 = 31474246
647 + 31473599 = 31474246

Showing the first eight; more decompositions exist.
