Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 545990, here are decompositions:

31 + 545959 = 545990
43 + 545947 = 545990
61 + 545929 = 545990
73 + 545917 = 545990
79 + 545911 = 545990
97 + 545893 = 545990
127 + 545863 = 545990
163 + 545827 = 545990

Showing the first eight; more decompositions exist.
