Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1039690, here are decompositions:

23 + 1039667 = 1039690
59 + 1039631 = 1039690
83 + 1039607 = 1039690
137 + 1039553 = 1039690
173 + 1039517 = 1039690
227 + 1039463 = 1039690
263 + 1039427 = 1039690
269 + 1039421 = 1039690

Showing the first eight; more decompositions exist.
