Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1008172, here are decompositions:

41 + 1008131 = 1008172
71 + 1008101 = 1008172
131 + 1008041 = 1008172
233 + 1007939 = 1008172
239 + 1007933 = 1008172
251 + 1007921 = 1008172
281 + 1007891 = 1008172
311 + 1007861 = 1008172

Showing the first eight; more decompositions exist.
