Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990832, here are decompositions:

23 + 990809 = 990832
71 + 990761 = 990832
113 + 990719 = 990832
233 + 990599 = 990832
239 + 990593 = 990832
443 + 990389 = 990832
449 + 990383 = 990832
461 + 990371 = 990832

Showing the first eight; more decompositions exist.
