Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1012890, here are decompositions:

29 + 1012861 = 1012890
59 + 1012831 = 1012890
61 + 1012829 = 1012890
79 + 1012811 = 1012890
101 + 1012789 = 1012890
127 + 1012763 = 1012890
139 + 1012751 = 1012890
157 + 1012733 = 1012890

Showing the first eight; more decompositions exist.
