Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997972, here are decompositions:

11 + 997961 = 997972
23 + 997949 = 997972
83 + 997889 = 997972
179 + 997793 = 997972
233 + 997739 = 997972
383 + 997589 = 997972
389 + 997583 = 997972
419 + 997553 = 997972

Showing the first eight; more decompositions exist.
