Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981364, here are decompositions:

53 + 981311 = 981364
101 + 981263 = 981364
191 + 981173 = 981364
227 + 981137 = 981364
347 + 981017 = 981364
353 + 981011 = 981364
401 + 980963 = 981364
443 + 980921 = 981364

Showing the first eight; more decompositions exist.
