Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 991302, here are decompositions:

29 + 991273 = 991302
41 + 991261 = 991302
73 + 991229 = 991302
79 + 991223 = 991302
101 + 991201 = 991302
131 + 991171 = 991302
173 + 991129 = 991302
211 + 991091 = 991302

Showing the first eight; more decompositions exist.
