Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540972, here are decompositions:

11 + 540961 = 540972
71 + 540901 = 540972
101 + 540871 = 540972
109 + 540863 = 540972
149 + 540823 = 540972
163 + 540809 = 540972
191 + 540781 = 540972
193 + 540779 = 540972

Showing the first eight; more decompositions exist.
