Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540128, here are decompositions:

7 + 540121 = 540128
67 + 540061 = 540128
181 + 539947 = 540128
229 + 539899 = 540128
331 + 539797 = 540128
367 + 539761 = 540128
487 + 539641 = 540128
499 + 539629 = 540128

Showing the first eight; more decompositions exist.
