Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540446, here are decompositions:

13 + 540433 = 540446
73 + 540373 = 540446
79 + 540367 = 540446
97 + 540349 = 540446
103 + 540343 = 540446
139 + 540307 = 540446
163 + 540283 = 540446
229 + 540217 = 540446

Showing the first eight; more decompositions exist.
