Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483310, here are decompositions:

3 + 31483307 = 31483310
73 + 31483237 = 31483310
97 + 31483213 = 31483310
193 + 31483117 = 31483310
223 + 31483087 = 31483310
241 + 31483069 = 31483310
307 + 31483003 = 31483310
337 + 31482973 = 31483310

Showing the first eight; more decompositions exist.
