Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 942400, here are decompositions:

29 + 942371 = 942400
59 + 942341 = 942400
83 + 942317 = 942400
89 + 942311 = 942400
131 + 942269 = 942400
233 + 942167 = 942400
257 + 942143 = 942400
359 + 942041 = 942400

Showing the first eight; more decompositions exist.
