Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453560, here are decompositions:

31 + 31453529 = 31453560
37 + 31453523 = 31453560
53 + 31453507 = 31453560
59 + 31453501 = 31453560
97 + 31453463 = 31453560
113 + 31453447 = 31453560
139 + 31453421 = 31453560
167 + 31453393 = 31453560

Showing the first eight; more decompositions exist.
