Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 979872, here are decompositions:

41 + 979831 = 979872
53 + 979819 = 979872
163 + 979709 = 979872
181 + 979691 = 979872
331 + 979541 = 979872
353 + 979519 = 979872
401 + 979471 = 979872
433 + 979439 = 979872

Showing the first eight; more decompositions exist.
