Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540830, here are decompositions:

7 + 540823 = 540830
61 + 540769 = 540830
79 + 540751 = 540830
127 + 540703 = 540830
139 + 540691 = 540830
151 + 540679 = 540830
211 + 540619 = 540830
271 + 540559 = 540830

Showing the first eight; more decompositions exist.
