Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540042, here are decompositions:

179 + 539863 = 540042
193 + 539849 = 540042
199 + 539843 = 540042
281 + 539761 = 540042
313 + 539729 = 540042
331 + 539711 = 540042
379 + 539663 = 540042
389 + 539653 = 540042

Showing the first eight; more decompositions exist.
