Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 941780, here are decompositions:

43 + 941737 = 941780
79 + 941701 = 941780
97 + 941683 = 941780
109 + 941671 = 941780
127 + 941653 = 941780
139 + 941641 = 941780
163 + 941617 = 941780
181 + 941599 = 941780

Showing the first eight; more decompositions exist.
