Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 991304, here are decompositions:

31 + 991273 = 991304
43 + 991261 = 991304
103 + 991201 = 991304
157 + 991147 = 991304
241 + 991063 = 991304
277 + 991027 = 991304
331 + 990973 = 991304
337 + 990967 = 991304

Showing the first eight; more decompositions exist.
