Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576372, here are decompositions:

5 + 31576367 = 31576372
83 + 31576289 = 31576372
89 + 31576283 = 31576372
131 + 31576241 = 31576372
173 + 31576199 = 31576372
251 + 31576121 = 31576372
281 + 31576091 = 31576372
449 + 31575923 = 31576372

Showing the first eight; more decompositions exist.
