Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546542, here are decompositions:

59 + 31546483 = 31546542
73 + 31546469 = 31546542
149 + 31546393 = 31546542
173 + 31546369 = 31546542
191 + 31546351 = 31546542
193 + 31546349 = 31546542
239 + 31546303 = 31546542
241 + 31546301 = 31546542

Showing the first eight; more decompositions exist.
