Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1003156, here are decompositions:

23 + 1003133 = 1003156
47 + 1003109 = 1003156
53 + 1003103 = 1003156
59 + 1003097 = 1003156
107 + 1003049 = 1003156
137 + 1003019 = 1003156
227 + 1002929 = 1003156
239 + 1002917 = 1003156

Showing the first eight; more decompositions exist.
