Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 991362, here are decompositions:

5 + 991357 = 991362
19 + 991343 = 991362
89 + 991273 = 991362
101 + 991261 = 991362
139 + 991223 = 991362
181 + 991181 = 991362
191 + 991171 = 991362
233 + 991129 = 991362

Showing the first eight; more decompositions exist.
