Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028930, here are decompositions:

37 + 1028893 = 1028930
127 + 1028803 = 1028930
157 + 1028773 = 1028930
181 + 1028749 = 1028930
193 + 1028737 = 1028930
283 + 1028647 = 1028930
313 + 1028617 = 1028930
349 + 1028581 = 1028930

Showing the first eight; more decompositions exist.
