Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554914, here are decompositions:

31 + 31554883 = 31554914
73 + 31554841 = 31554914
103 + 31554811 = 31554914
277 + 31554637 = 31554914
283 + 31554631 = 31554914
331 + 31554583 = 31554914
373 + 31554541 = 31554914
397 + 31554517 = 31554914

Showing the first eight; more decompositions exist.
