Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 991282, here are decompositions:

53 + 991229 = 991282
59 + 991223 = 991282
101 + 991181 = 991282
191 + 991091 = 991282
239 + 991043 = 991282
251 + 991031 = 991282
293 + 990989 = 991282
359 + 990923 = 991282

Showing the first eight; more decompositions exist.
