Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 991846, here are decompositions:

29 + 991817 = 991846
113 + 991733 = 991846
227 + 991619 = 991846
239 + 991607 = 991846
347 + 991499 = 991846
353 + 991493 = 991846
419 + 991427 = 991846
503 + 991343 = 991846

Showing the first eight; more decompositions exist.
