Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 939782, here are decompositions:

13 + 939769 = 939782
43 + 939739 = 939782
271 + 939511 = 939782
313 + 939469 = 939782
331 + 939451 = 939782
409 + 939373 = 939782
421 + 939361 = 939782
433 + 939349 = 939782

Showing the first eight; more decompositions exist.
