Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453608, here are decompositions:

31 + 31453577 = 31453608
37 + 31453571 = 31453608
79 + 31453529 = 31453608
101 + 31453507 = 31453608
107 + 31453501 = 31453608
181 + 31453427 = 31453608
359 + 31453249 = 31453608
367 + 31453241 = 31453608

Showing the first eight; more decompositions exist.
