Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554796, here are decompositions:

5 + 31554791 = 31554796
47 + 31554749 = 31554796
137 + 31554659 = 31554796
179 + 31554617 = 31554796
227 + 31554569 = 31554796
257 + 31554539 = 31554796
269 + 31554527 = 31554796
347 + 31554449 = 31554796

Showing the first eight; more decompositions exist.
