Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540990, here are decompositions:

29 + 540961 = 540990
83 + 540907 = 540990
89 + 540901 = 540990
113 + 540877 = 540990
127 + 540863 = 540990
139 + 540851 = 540990
167 + 540823 = 540990
181 + 540809 = 540990

Showing the first eight; more decompositions exist.
