Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1008178, here are decompositions:

47 + 1008131 = 1008178
137 + 1008041 = 1008178
239 + 1007939 = 1008178
257 + 1007921 = 1008178
317 + 1007861 = 1008178
359 + 1007819 = 1008178
389 + 1007789 = 1008178
419 + 1007759 = 1008178

Showing the first eight; more decompositions exist.
