Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 942890, here are decompositions:

7 + 942883 = 942890
31 + 942859 = 942890
37 + 942853 = 942890
43 + 942847 = 942890
79 + 942811 = 942890
103 + 942787 = 942890
127 + 942763 = 942890
163 + 942727 = 942890

Showing the first eight; more decompositions exist.
