Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 492880, here are decompositions:

41 + 492839 = 492880
149 + 492731 = 492880
173 + 492707 = 492880
233 + 492647 = 492880
239 + 492641 = 492880
251 + 492629 = 492880
263 + 492617 = 492880
293 + 492587 = 492880

Showing the first eight; more decompositions exist.
