Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997012, here are decompositions:

11 + 997001 = 997012
59 + 996953 = 997012
113 + 996899 = 997012
131 + 996881 = 997012
383 + 996629 = 997012
449 + 996563 = 997012
461 + 996551 = 997012
683 + 996329 = 997012

Showing the first eight; more decompositions exist.
