Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453506, here are decompositions:

5 + 31453501 = 31453506
23 + 31453483 = 31453506
43 + 31453463 = 31453506
59 + 31453447 = 31453506
79 + 31453427 = 31453506
113 + 31453393 = 31453506
173 + 31453333 = 31453506
223 + 31453283 = 31453506

Showing the first eight; more decompositions exist.
