Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1045642, here are decompositions:

71 + 1045571 = 1045642
83 + 1045559 = 1045642
113 + 1045529 = 1045642
149 + 1045493 = 1045642
173 + 1045469 = 1045642
233 + 1045409 = 1045642
251 + 1045391 = 1045642
293 + 1045349 = 1045642

Showing the first eight; more decompositions exist.
