Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483400, here are decompositions:

31 + 31483369 = 31483400
73 + 31483327 = 31483400
139 + 31483261 = 31483400
163 + 31483237 = 31483400
283 + 31483117 = 31483400
307 + 31483093 = 31483400
313 + 31483087 = 31483400
331 + 31483069 = 31483400

Showing the first eight; more decompositions exist.
