Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987418, here are decompositions:

167 + 987251 = 987418
191 + 987227 = 987418
227 + 987191 = 987418
317 + 987101 = 987418
389 + 987029 = 987418
491 + 986927 = 987418
569 + 986849 = 987418
599 + 986819 = 987418

Showing the first eight; more decompositions exist.
