Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 941820, here are decompositions:

7 + 941813 = 941820
29 + 941791 = 941820
67 + 941753 = 941820
73 + 941747 = 941820
79 + 941741 = 941820
83 + 941737 = 941820
97 + 941723 = 941820
137 + 941683 = 941820

Showing the first eight; more decompositions exist.
