Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1046428, here are decompositions:

29 + 1046399 = 1046428
59 + 1046369 = 1046428
191 + 1046237 = 1046428
239 + 1046189 = 1046428
347 + 1046081 = 1046428
359 + 1046069 = 1046428
431 + 1045997 = 1046428
521 + 1045907 = 1046428

Showing the first eight; more decompositions exist.
