Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540146, here are decompositions:

7 + 540139 = 540146
67 + 540079 = 540146
199 + 539947 = 540146
283 + 539863 = 540146
307 + 539839 = 540146
349 + 539797 = 540146
433 + 539713 = 540146
613 + 539533 = 540146

Showing the first eight; more decompositions exist.
