Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1045880, here are decompositions:

61 + 1045819 = 1045880
79 + 1045801 = 1045880
151 + 1045729 = 1045880
229 + 1045651 = 1045880
307 + 1045573 = 1045880
331 + 1045549 = 1045880
337 + 1045543 = 1045880
373 + 1045507 = 1045880

Showing the first eight; more decompositions exist.
