Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546450, here are decompositions:

29 + 31546421 = 31546450
101 + 31546349 = 31546450
113 + 31546337 = 31546450
149 + 31546301 = 31546450
167 + 31546283 = 31546450
233 + 31546217 = 31546450
251 + 31546199 = 31546450
263 + 31546187 = 31546450

Showing the first eight; more decompositions exist.
