Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990826, here are decompositions:

17 + 990809 = 990826
29 + 990797 = 990826
59 + 990767 = 990826
107 + 990719 = 990826
227 + 990599 = 990826
233 + 990593 = 990826
443 + 990383 = 990826
449 + 990377 = 990826

Showing the first eight; more decompositions exist.
