Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 939722, here are decompositions:

61 + 939661 = 939722
73 + 939649 = 939722
109 + 939613 = 939722
211 + 939511 = 939722
271 + 939451 = 939722
283 + 939439 = 939722
331 + 939391 = 939722
349 + 939373 = 939722

Showing the first eight; more decompositions exist.
