Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1045978, here are decompositions:

71 + 1045907 = 1045978
137 + 1045841 = 1045978
149 + 1045829 = 1045978
179 + 1045799 = 1045978
239 + 1045739 = 1045978
251 + 1045727 = 1045978
419 + 1045559 = 1045978
431 + 1045547 = 1045978

Showing the first eight; more decompositions exist.
