Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483358, here are decompositions:

7 + 31483351 = 31483358
31 + 31483327 = 31483358
97 + 31483261 = 31483358
241 + 31483117 = 31483358
271 + 31483087 = 31483358
307 + 31483051 = 31483358
367 + 31482991 = 31483358
499 + 31482859 = 31483358

Showing the first eight; more decompositions exist.
