Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020730, here are decompositions:

23 + 1020707 = 1020730
41 + 1020689 = 1020730
47 + 1020683 = 1020730
131 + 1020599 = 1020730
173 + 1020557 = 1020730
239 + 1020491 = 1020730
311 + 1020419 = 1020730
317 + 1020413 = 1020730

Showing the first eight; more decompositions exist.
