Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 938424, here are decompositions:

31 + 938393 = 938424
37 + 938387 = 938424
73 + 938351 = 938424
83 + 938341 = 938424
101 + 938323 = 938424
131 + 938293 = 938424
167 + 938257 = 938424
173 + 938251 = 938424

Showing the first eight; more decompositions exist.
