Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540998, here are decompositions:

37 + 540961 = 540998
97 + 540901 = 540998
127 + 540871 = 540998
229 + 540769 = 540998
307 + 540691 = 540998
379 + 540619 = 540998
421 + 540577 = 540998
439 + 540559 = 540998

Showing the first eight; more decompositions exist.
