Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453584, here are decompositions:

7 + 31453577 = 31453584
13 + 31453571 = 31453584
61 + 31453523 = 31453584
83 + 31453501 = 31453584
101 + 31453483 = 31453584
137 + 31453447 = 31453584
157 + 31453427 = 31453584
163 + 31453421 = 31453584

Showing the first eight; more decompositions exist.
