Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454556, here are decompositions:

43 + 31454513 = 31454556
59 + 31454497 = 31454556
73 + 31454483 = 31454556
167 + 31454389 = 31454556
173 + 31454383 = 31454556
179 + 31454377 = 31454556
293 + 31454263 = 31454556
307 + 31454249 = 31454556

Showing the first eight; more decompositions exist.
