Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1008190, here are decompositions:

3 + 1008187 = 1008190
59 + 1008131 = 1008190
89 + 1008101 = 1008190
149 + 1008041 = 1008190
173 + 1008017 = 1008190
233 + 1007957 = 1008190
251 + 1007939 = 1008190
257 + 1007933 = 1008190

Showing the first eight; more decompositions exist.
