Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540858, here are decompositions:

7 + 540851 = 540858
79 + 540779 = 540858
89 + 540769 = 540858
107 + 540751 = 540858
167 + 540691 = 540858
179 + 540679 = 540858
181 + 540677 = 540858
229 + 540629 = 540858

Showing the first eight; more decompositions exist.
