Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453504, here are decompositions:

3 + 31453501 = 31453504
41 + 31453463 = 31453504
83 + 31453421 = 31453504
113 + 31453391 = 31453504
263 + 31453241 = 31453504
311 + 31453193 = 31453504
347 + 31453157 = 31453504
653 + 31452851 = 31453504

Showing the first eight; more decompositions exist.
