Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554944, here are decompositions:

61 + 31554883 = 31554944
103 + 31554841 = 31554944
277 + 31554667 = 31554944
307 + 31554637 = 31554944
313 + 31554631 = 31554944
331 + 31554613 = 31554944
373 + 31554571 = 31554944
433 + 31554511 = 31554944

Showing the first eight; more decompositions exist.
