Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453556, here are decompositions:

73 + 31453483 = 31453556
109 + 31453447 = 31453556
163 + 31453393 = 31453556
223 + 31453333 = 31453556
307 + 31453249 = 31453556
349 + 31453207 = 31453556
397 + 31453159 = 31453556
613 + 31452943 = 31453556

Showing the first eight; more decompositions exist.
