Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1047980, here are decompositions:

19 + 1047961 = 1047980
97 + 1047883 = 1047980
139 + 1047841 = 1047980
229 + 1047751 = 1047980
277 + 1047703 = 1047980
313 + 1047667 = 1047980
331 + 1047649 = 1047980
421 + 1047559 = 1047980

Showing the first eight; more decompositions exist.
