Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458998, here are decompositions:

31 + 31458967 = 31458998
61 + 31458937 = 31458998
97 + 31458901 = 31458998
199 + 31458799 = 31458998
211 + 31458787 = 31458998
331 + 31458667 = 31458998
367 + 31458631 = 31458998
397 + 31458601 = 31458998

Showing the first eight; more decompositions exist.
