Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 541018, here are decompositions:

11 + 541007 = 541018
17 + 541001 = 541018
29 + 540989 = 541018
167 + 540851 = 541018
239 + 540779 = 541018
389 + 540629 = 541018
419 + 540599 = 541018
431 + 540587 = 541018

Showing the first eight; more decompositions exist.
