Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 991364, here are decompositions:

7 + 991357 = 991364
37 + 991327 = 991364
103 + 991261 = 991364
163 + 991201 = 991364
193 + 991171 = 991364
307 + 991057 = 991364
337 + 991027 = 991364
397 + 990967 = 991364

Showing the first eight; more decompositions exist.
