Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1061388, here are decompositions:

11 + 1061377 = 1061388
71 + 1061317 = 1061388
101 + 1061287 = 1061388
109 + 1061279 = 1061388
127 + 1061261 = 1061388
137 + 1061251 = 1061388
199 + 1061189 = 1061388
239 + 1061149 = 1061388

Showing the first eight; more decompositions exist.
