Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042864, here are decompositions:

3 + 1042861 = 1042864
83 + 1042781 = 1042864
131 + 1042733 = 1042864
233 + 1042631 = 1042864
257 + 1042607 = 1042864
281 + 1042583 = 1042864
293 + 1042571 = 1042864
491 + 1042373 = 1042864

Showing the first eight; more decompositions exist.
