Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540986, here are decompositions:

79 + 540907 = 540986
109 + 540877 = 540986
163 + 540823 = 540986
283 + 540703 = 540986
307 + 540679 = 540986
367 + 540619 = 540986
373 + 540613 = 540986
409 + 540577 = 540986

Showing the first eight; more decompositions exist.
