Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554928, here are decompositions:

29 + 31554899 = 31554928
131 + 31554797 = 31554928
137 + 31554791 = 31554928
179 + 31554749 = 31554928
257 + 31554671 = 31554928
269 + 31554659 = 31554928
311 + 31554617 = 31554928
359 + 31554569 = 31554928

Showing the first eight; more decompositions exist.
