Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31513432, here are decompositions:

29 + 31513403 = 31513432
59 + 31513373 = 31513432
101 + 31513331 = 31513432
173 + 31513259 = 31513432
239 + 31513193 = 31513432
359 + 31513073 = 31513432
383 + 31513049 = 31513432
563 + 31512869 = 31513432

Showing the first eight; more decompositions exist.
