Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 492806, here are decompositions:

7 + 492799 = 492806
37 + 492769 = 492806
43 + 492763 = 492806
283 + 492523 = 492806
397 + 492409 = 492806
409 + 492397 = 492806
487 + 492319 = 492806
739 + 492067 = 492806

Showing the first eight; more decompositions exist.
