Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453848, here are decompositions:

7 + 31453841 = 31453848
137 + 31453711 = 31453848
149 + 31453699 = 31453848
197 + 31453651 = 31453848
271 + 31453577 = 31453848
277 + 31453571 = 31453848
347 + 31453501 = 31453848
401 + 31453447 = 31453848

Showing the first eight; more decompositions exist.
