Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 492488, here are decompositions:

67 + 492421 = 492488
79 + 492409 = 492488
421 + 492067 = 492488
631 + 491857 = 492488
691 + 491797 = 492488
751 + 491737 = 492488
757 + 491731 = 492488
769 + 491719 = 492488

Showing the first eight; more decompositions exist.
