Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576508, here are decompositions:

31 + 31576477 = 31576508
97 + 31576411 = 31576508
157 + 31576351 = 31576508
241 + 31576267 = 31576508
277 + 31576231 = 31576508
307 + 31576201 = 31576508
421 + 31576087 = 31576508
499 + 31576009 = 31576508

Showing the first eight; more decompositions exist.
