Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1044920, here are decompositions:

31 + 1044889 = 1044920
43 + 1044877 = 1044920
61 + 1044859 = 1044920
73 + 1044847 = 1044920
109 + 1044811 = 1044920
139 + 1044781 = 1044920
181 + 1044739 = 1044920
193 + 1044727 = 1044920

Showing the first eight; more decompositions exist.
