Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1039840, here are decompositions:

3 + 1039837 = 1039840
17 + 1039823 = 1039840
23 + 1039817 = 1039840
41 + 1039799 = 1039840
71 + 1039769 = 1039840
107 + 1039733 = 1039840
173 + 1039667 = 1039840
233 + 1039607 = 1039840

Showing the first eight; more decompositions exist.
