Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453696, here are decompositions:

17 + 31453679 = 31453696
167 + 31453529 = 31453696
173 + 31453523 = 31453696
233 + 31453463 = 31453696
269 + 31453427 = 31453696
503 + 31453193 = 31453696
563 + 31453133 = 31453696
719 + 31452977 = 31453696

Showing the first eight; more decompositions exist.
