Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 938740, here are decompositions:

59 + 938681 = 938740
149 + 938591 = 938740
167 + 938573 = 938740
233 + 938507 = 938740
281 + 938459 = 938740
293 + 938447 = 938740
347 + 938393 = 938740
353 + 938387 = 938740

Showing the first eight; more decompositions exist.
