Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042888, here are decompositions:

59 + 1042829 = 1042888
89 + 1042799 = 1042888
107 + 1042781 = 1042888
179 + 1042709 = 1042888
257 + 1042631 = 1042888
269 + 1042619 = 1042888
281 + 1042607 = 1042888
311 + 1042577 = 1042888

Showing the first eight; more decompositions exist.
