Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981476, here are decompositions:

3 + 981473 = 981476
37 + 981439 = 981476
79 + 981397 = 981476
103 + 981373 = 981476
157 + 981319 = 981476
193 + 981283 = 981476
277 + 981199 = 981476
337 + 981139 = 981476

Showing the first eight; more decompositions exist.
