Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 940580, here are decompositions:

7 + 940573 = 940580
31 + 940549 = 940580
37 + 940543 = 940580
79 + 940501 = 940580
97 + 940483 = 940580
103 + 940477 = 940580
181 + 940399 = 940580
211 + 940369 = 940580

Showing the first eight; more decompositions exist.
