Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496446, here are decompositions:

5 + 31496441 = 31496446
17 + 31496429 = 31496446
29 + 31496417 = 31496446
227 + 31496219 = 31496446
347 + 31496099 = 31496446
389 + 31496057 = 31496446
419 + 31496027 = 31496446
467 + 31495979 = 31496446

Showing the first eight; more decompositions exist.
