Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 942990, here are decompositions:

7 + 942983 = 942990
11 + 942979 = 942990
47 + 942943 = 942990
73 + 942917 = 942990
89 + 942901 = 942990
101 + 942889 = 942990
107 + 942883 = 942990
131 + 942859 = 942990

Showing the first eight; more decompositions exist.
