Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 991774, here are decompositions:

23 + 991751 = 991774
41 + 991733 = 991774
71 + 991703 = 991774
131 + 991643 = 991774
167 + 991607 = 991774
227 + 991547 = 991774
233 + 991541 = 991774
263 + 991511 = 991774

Showing the first eight; more decompositions exist.
