Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458698, here are decompositions:

31 + 31458667 = 31458698
67 + 31458631 = 31458698
97 + 31458601 = 31458698
109 + 31458589 = 31458698
157 + 31458541 = 31458698
211 + 31458487 = 31458698
367 + 31458331 = 31458698
421 + 31458277 = 31458698

Showing the first eight; more decompositions exist.
