Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1048978, here are decompositions:

59 + 1048919 = 1048978
89 + 1048889 = 1048978
101 + 1048877 = 1048978
131 + 1048847 = 1048978
149 + 1048829 = 1048978
179 + 1048799 = 1048978
257 + 1048721 = 1048978
269 + 1048709 = 1048978

Showing the first eight; more decompositions exist.
