Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 942390, here are decompositions:

19 + 942371 = 942390
23 + 942367 = 942390
73 + 942317 = 942390
79 + 942311 = 942390
89 + 942301 = 942390
167 + 942223 = 942390
173 + 942217 = 942390
191 + 942199 = 942390

Showing the first eight; more decompositions exist.
