Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 470642, here are decompositions:

43 + 470599 = 470642
103 + 470539 = 470642
181 + 470461 = 470642
199 + 470443 = 470642
229 + 470413 = 470642
283 + 470359 = 470642
379 + 470263 = 470642
433 + 470209 = 470642

Showing the first eight; more decompositions exist.
