Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540902, here are decompositions:

31 + 540871 = 540902
79 + 540823 = 540902
151 + 540751 = 540902
199 + 540703 = 540902
211 + 540691 = 540902
223 + 540679 = 540902
283 + 540619 = 540902
433 + 540469 = 540902

Showing the first eight; more decompositions exist.
