Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 938684, here are decompositions:

3 + 938681 = 938684
7 + 938677 = 938684
67 + 938617 = 938684
73 + 938611 = 938684
151 + 938533 = 938684
193 + 938491 = 938684
337 + 938347 = 938684
421 + 938263 = 938684

Showing the first eight; more decompositions exist.
