Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997122, here are decompositions:

11 + 997111 = 997122
13 + 997109 = 997122
19 + 997103 = 997122
23 + 997099 = 997122
31 + 997091 = 997122
41 + 997081 = 997122
53 + 997069 = 997122
79 + 997043 = 997122

Showing the first eight; more decompositions exist.
