Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 993908, here are decompositions:

67 + 993841 = 993908
127 + 993781 = 993908
229 + 993679 = 993908
367 + 993541 = 993908
457 + 993451 = 993908
541 + 993367 = 993908
661 + 993247 = 993908
691 + 993217 = 993908

Showing the first eight; more decompositions exist.
