Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554934, here are decompositions:

41 + 31554893 = 31554934
71 + 31554863 = 31554934
83 + 31554851 = 31554934
137 + 31554797 = 31554934
263 + 31554671 = 31554934
293 + 31554641 = 31554934
317 + 31554617 = 31554934
461 + 31554473 = 31554934

Showing the first eight; more decompositions exist.
