Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997140, here are decompositions:

17 + 997123 = 997140
19 + 997121 = 997140
29 + 997111 = 997140
31 + 997109 = 997140
37 + 997103 = 997140
41 + 997099 = 997140
43 + 997097 = 997140
59 + 997081 = 997140

Showing the first eight; more decompositions exist.
