Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546506, here are decompositions:

23 + 31546483 = 31546506
37 + 31546469 = 31546506
113 + 31546393 = 31546506
137 + 31546369 = 31546506
157 + 31546349 = 31546506
223 + 31546283 = 31546506
227 + 31546279 = 31546506
239 + 31546267 = 31546506

Showing the first eight; more decompositions exist.
