Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 942520, here are decompositions:

11 + 942509 = 942520
41 + 942479 = 942520
71 + 942449 = 942520
83 + 942437 = 942520
149 + 942371 = 942520
179 + 942341 = 942520
251 + 942269 = 942520
263 + 942257 = 942520

Showing the first eight; more decompositions exist.
