Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31519552, here are decompositions:

89 + 31519463 = 31519552
149 + 31519403 = 31519552
173 + 31519379 = 31519552
263 + 31519289 = 31519552
353 + 31519199 = 31519552
359 + 31519193 = 31519552
401 + 31519151 = 31519552
431 + 31519121 = 31519552

Showing the first eight; more decompositions exist.
