Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1039864, here are decompositions:

41 + 1039823 = 1039864
47 + 1039817 = 1039864
101 + 1039763 = 1039864
131 + 1039733 = 1039864
197 + 1039667 = 1039864
233 + 1039631 = 1039864
257 + 1039607 = 1039864
311 + 1039553 = 1039864

Showing the first eight; more decompositions exist.
