Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997846, here are decompositions:

53 + 997793 = 997846
107 + 997739 = 997846
197 + 997649 = 997846
257 + 997589 = 997846
263 + 997583 = 997846
293 + 997553 = 997846
383 + 997463 = 997846
419 + 997427 = 997846

Showing the first eight; more decompositions exist.
