Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 940640, here are decompositions:

67 + 940573 = 940640
97 + 940543 = 940640
109 + 940531 = 940640
139 + 940501 = 940640
157 + 940483 = 940640
163 + 940477 = 940640
241 + 940399 = 940640
271 + 940369 = 940640

Showing the first eight; more decompositions exist.
