Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 942920, here are decompositions:

3 + 942917 = 942920
19 + 942901 = 942920
31 + 942889 = 942920
37 + 942883 = 942920
61 + 942859 = 942920
67 + 942853 = 942920
73 + 942847 = 942920
109 + 942811 = 942920

Showing the first eight; more decompositions exist.
