Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1003188, here are decompositions:

47 + 1003141 = 1003188
79 + 1003109 = 1003188
97 + 1003091 = 1003188
101 + 1003087 = 1003188
139 + 1003049 = 1003188
149 + 1003039 = 1003188
257 + 1002931 = 1003188
271 + 1002917 = 1003188

Showing the first eight; more decompositions exist.
