Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453554, here are decompositions:

31 + 31453523 = 31453554
47 + 31453507 = 31453554
53 + 31453501 = 31453554
71 + 31453483 = 31453554
107 + 31453447 = 31453554
127 + 31453427 = 31453554
163 + 31453391 = 31453554
193 + 31453361 = 31453554

Showing the first eight; more decompositions exist.
