Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1029830, here are decompositions:

3 + 1029827 = 1029830
7 + 1029823 = 1029830
73 + 1029757 = 1029830
79 + 1029751 = 1029830
229 + 1029601 = 1029830
283 + 1029547 = 1029830
313 + 1029517 = 1029830
331 + 1029499 = 1029830

Showing the first eight; more decompositions exist.
