Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540890, here are decompositions:

13 + 540877 = 540890
19 + 540871 = 540890
67 + 540823 = 540890
109 + 540781 = 540890
139 + 540751 = 540890
193 + 540697 = 540890
199 + 540691 = 540890
211 + 540679 = 540890

Showing the first eight; more decompositions exist.
