Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 940880, here are decompositions:

67 + 940813 = 940880
79 + 940801 = 940880
97 + 940783 = 940880
211 + 940669 = 940880
307 + 940573 = 940880
331 + 940549 = 940880
337 + 940543 = 940880
349 + 940531 = 940880

Showing the first eight; more decompositions exist.
