Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 492278, here are decompositions:

211 + 492067 = 492278
271 + 492007 = 492278
379 + 491899 = 492278
421 + 491857 = 492278
541 + 491737 = 492278
547 + 491731 = 492278
571 + 491707 = 492278
601 + 491677 = 492278

Showing the first eight; more decompositions exist.
