Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 940688, here are decompositions:

19 + 940669 = 940688
139 + 940549 = 940688
157 + 940531 = 940688
211 + 940477 = 940688
337 + 940351 = 940688
409 + 940279 = 940688
439 + 940249 = 940688
487 + 940201 = 940688

Showing the first eight; more decompositions exist.
