Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458382, here are decompositions:

3 + 31458379 = 31458382
5 + 31458377 = 31458382
71 + 31458311 = 31458382
83 + 31458299 = 31458382
191 + 31458191 = 31458382
251 + 31458131 = 31458382
269 + 31458113 = 31458382
383 + 31457999 = 31458382

Showing the first eight; more decompositions exist.
