Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458914, here are decompositions:

7 + 31458907 = 31458914
13 + 31458901 = 31458914
127 + 31458787 = 31458914
211 + 31458703 = 31458914
271 + 31458643 = 31458914
283 + 31458631 = 31458914
307 + 31458607 = 31458914
313 + 31458601 = 31458914

Showing the first eight; more decompositions exist.
