Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 942490, here are decompositions:

11 + 942479 = 942490
41 + 942449 = 942490
53 + 942437 = 942490
89 + 942401 = 942490
149 + 942341 = 942490
173 + 942317 = 942490
179 + 942311 = 942490
233 + 942257 = 942490

Showing the first eight; more decompositions exist.
