Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 942478, here are decompositions:

29 + 942449 = 942478
41 + 942437 = 942478
107 + 942371 = 942478
137 + 942341 = 942478
167 + 942311 = 942478
311 + 942167 = 942478
461 + 942017 = 942478
479 + 941999 = 942478

Showing the first eight; more decompositions exist.
