Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987126, here are decompositions:

29 + 987097 = 987126
37 + 987089 = 987126
43 + 987083 = 987126
47 + 987079 = 987126
59 + 987067 = 987126
73 + 987053 = 987126
83 + 987043 = 987126
97 + 987029 = 987126

Showing the first eight; more decompositions exist.
