Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 938782, here are decompositions:

101 + 938681 = 938782
191 + 938591 = 938782
389 + 938393 = 938782
431 + 938351 = 938782
503 + 938279 = 938782
563 + 938219 = 938782
599 + 938183 = 938782
653 + 938129 = 938782

Showing the first eight; more decompositions exist.
