Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554446, here are decompositions:

13 + 31554433 = 31554446
37 + 31554409 = 31554446
109 + 31554337 = 31554446
163 + 31554283 = 31554446
283 + 31554163 = 31554446
373 + 31554073 = 31554446
433 + 31554013 = 31554446
463 + 31553983 = 31554446

Showing the first eight; more decompositions exist.
