Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 982438, here are decompositions:

101 + 982337 = 982438
137 + 982301 = 982438
167 + 982271 = 982438
227 + 982211 = 982438
251 + 982187 = 982438
491 + 981947 = 982438
641 + 981797 = 982438
839 + 981599 = 982438

Showing the first eight; more decompositions exist.
