Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540872, here are decompositions:

103 + 540769 = 540872
181 + 540691 = 540872
193 + 540679 = 540872
313 + 540559 = 540872
331 + 540541 = 540872
439 + 540433 = 540872
499 + 540373 = 540872
523 + 540349 = 540872

Showing the first eight; more decompositions exist.
