Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453536, here are decompositions:

7 + 31453529 = 31453536
13 + 31453523 = 31453536
29 + 31453507 = 31453536
53 + 31453483 = 31453536
73 + 31453463 = 31453536
89 + 31453447 = 31453536
109 + 31453427 = 31453536
269 + 31453267 = 31453536

Showing the first eight; more decompositions exist.
