Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1006388, here are decompositions:

37 + 1006351 = 1006388
79 + 1006309 = 1006388
109 + 1006279 = 1006388
139 + 1006249 = 1006388
151 + 1006237 = 1006388
157 + 1006231 = 1006388
199 + 1006189 = 1006388
211 + 1006177 = 1006388

Showing the first eight; more decompositions exist.
