Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546272, here are decompositions:

5 + 31546267 = 31546272
41 + 31546231 = 31546272
73 + 31546199 = 31546272
113 + 31546159 = 31546272
281 + 31545991 = 31546272
313 + 31545959 = 31546272
349 + 31545923 = 31546272
353 + 31545919 = 31546272

Showing the first eight; more decompositions exist.
