Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 938418, here are decompositions:

31 + 938387 = 938418
59 + 938359 = 938418
67 + 938351 = 938418
71 + 938347 = 938418
109 + 938309 = 938418
139 + 938279 = 938418
167 + 938251 = 938418
199 + 938219 = 938418

Showing the first eight; more decompositions exist.
