Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554258, here are decompositions:

17 + 31554241 = 31554258
59 + 31554199 = 31554258
79 + 31554179 = 31554258
97 + 31554161 = 31554258
137 + 31554121 = 31554258
181 + 31554077 = 31554258
271 + 31553987 = 31554258
457 + 31553801 = 31554258

Showing the first eight; more decompositions exist.
