Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 979972, here are decompositions:

3 + 979969 = 979972
23 + 979949 = 979972
53 + 979919 = 979972
83 + 979889 = 979972
89 + 979883 = 979972
263 + 979709 = 979972
281 + 979691 = 979972
419 + 979553 = 979972

Showing the first eight; more decompositions exist.
