Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 942942, here are decompositions:

41 + 942901 = 942942
43 + 942899 = 942942
53 + 942889 = 942942
59 + 942883 = 942942
73 + 942869 = 942942
83 + 942859 = 942942
89 + 942853 = 942942
131 + 942811 = 942942

Showing the first eight; more decompositions exist.
