Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022830, here are decompositions:

101 + 1022729 = 1022830
191 + 1022639 = 1022830
197 + 1022633 = 1022830
239 + 1022591 = 1022830
257 + 1022573 = 1022830
311 + 1022519 = 1022830
317 + 1022513 = 1022830
401 + 1022429 = 1022830

Showing the first eight; more decompositions exist.
