Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 940778, here are decompositions:

19 + 940759 = 940778
109 + 940669 = 940778
229 + 940549 = 940778
277 + 940501 = 940778
379 + 940399 = 940778
409 + 940369 = 940778
499 + 940279 = 940778
577 + 940201 = 940778

Showing the first eight; more decompositions exist.
